[bpt/guile.git] / libguile / ChangeLog

2003-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c: Partially undid my patch from 2003-05-31.  This patch
	caused the segfault referenced in the previous changelog entry.

2003-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* tags.h: Fixed comment about the immediate type code layout.

	* eval.c: Fixed handling of non-special instructions.  Without
	this patch, guile will segfault on (#\0) and similar instructions.

2003-06-05  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_max, scm_min): For inum, bignum and real, if other
	operand is NaN, then return NaN.  Also avoid passing NaN to mpz_cmp_d.

	* read.c (scm_input_error): Pass arg list parameter to scm_error_scm,
	rather than SCM_EOL.  Needed by "Unknown # object" case in scm_lreadr.
	
2003-06-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
	SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
	SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and
	generalized it to apply not only to C level functions but also to
	scheme level functions.

	* debug.c, debug.h, eval.c (make-iloc, scm_make_iloc, iloc?,
	scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?,
	scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to
	eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
	only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
	respectively.

	* deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
	SCM_IDSTMSK): Deprecated.  The macro definitions are moved from
	eval.h into eval.c and a copy is placed into deprecated.h.

	* eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
	into eval.c. This definition was not part of the API in any
	officially released version of guile and thus does not need to go
	through a phase of deprecation.

2003-06-02  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* deprecated.c, deprecated.h, eval.c, eval.h (scm_s_expression,
	scm_s_test, scm_s_body, scm_s_bindings, scm_s_variable,
	scm_s_clauses, scm_s_formals): Deprecated.  In eval.c the
	definitions are make static and renamed from scm_s_xxx to s_xxx.
	In deprecated.c the original definitions are copied.

	* deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL,
	SCM_XEVALCAR): Deprecated.  The macro definitions are moved from
	eval.h into eval.c and a copy (slightly modified to work in user
	code) is placed into deprecated.h.

	* eval.c: Use the local static s_xxx definitions instead of the
	scm_s_xxx definitions throughout.

2003-06-01  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	This set of patches separates the representation of the cxr family
	of functions (car, cdr etc.) from the dsubr family of functions
	(i. e. functions that take a double precision floating point
	argument).  Further, the algorithm for handling the cxr function
	is improved.

	* eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_1), numbers.c
	(scm_asinh, scm_acosh, scm_atanh, scm_truncate, scm_round, floor,
	ceil, sqrt, fabs, exp, log, sin, cos, tan, asin, acos, atan, sinh,
	cosh, tanh), objects.c (scm_class_of), procprop.c
	(scm_i_procedure_arity), ramap.c (scm_array_map_x), tags.h
	(scm_tc7_dsubr, scm_tcs_subrs): Introduce scm_tc7_dsubr as new
	typecode for the dsubr family of functions.

	* ramap.c (ramap_cxr, ramap_dsubr): Renamed ramap_cxr to
	ramap_dsubr.

	* eval.c (SCM_CEVAL, SCM_APPLY, call_cxr_1), pairs.c
	(scm_init_pairs): Make use of the (now usable) second cell element
	of a scm_tc7_cxr function to implement the cxr family of functions
	more efficiently.

2003-05-31  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_0,
	scm_trampoline_1, scm_trampoline_2): Postpone error cases to the
	end of an if-else-if-sequence of checks.

2003-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL): Improved readability of call-with-values
	execution.  Generalize apply_closure to apply_proc and use that
	for call-with-values.

2003-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL): Avoid one level of indirection when applying
	a non closure.

2003-05-30  Stefan Jahn  <stefan@lkcc.org>

	* posix.c (s_scm_putenv): Use the new HAVE_UNSETENV 
	appropriately for mingw32 hosts.

	* numbers.h: Defining copysign(), isnan() and finite() to
	be prefixed by a single '_' for mingw32 hosts.

2003-05-30  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (z_negative_one): New variable.
	(scm_init_numbers): Initialize it.
	(scm_logcount): Use it and mpz_hamdist to count zeros for negatives.

2003-05-29  Stefan Jahn  <stefan@lkcc.org>

	* win32-dirent.c: Use malloc() instead of scm_malloc().

	* stime.c (s_scm_strftime): Add a type cast to avoid compiler
	warning.

	* posix.c (s_scm_putenv): Disable use of unsetenv() for the
	mingw32 build.

	* modules.c (s_scm_module_import_interface): Renamed local
	variable interface to _interface.  Seems like 'interface'
	is a special compiler directive for the mingw32 compiler.

	* mkstemp.c: Provide prototype to avoid compiler warning.

	* load.c (s_scm_search_path): Fixed absolute and relative
	path detections for native Windows platforms.

	* gc.h, threads.h: Export some more symbols using SCM_API (necessary 
	to build on mingw32).

	* gc-freelist.c ("s_scm_map_free_list", 
	"s_scm_gc_set_debug_check_freelist_x"): Fixed use of FUNC_NAME.

	* fports.c (fport_fill_input): Disable use of 
	fport_wait_for_input() on Win32 platforms.

	* filesys.c (s_scm_basename): Fixed __MINGW32__ code.

	* Makefile.am: Modified some rules for cross compiling.

2003-05-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_CEVAL): In case of an application, all checks for a
	proper function object and the correct number of arguments are now
	performed in the application part of SCM_CEVAL.

	(scm_badformalsp):  Removed.

2003-05-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* deprecated.c (scm_read_and_eval_x):  Fixed C99-ism.

2003-05-22  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* num2integral.i.c (NUM2INTEGRAL): Avoid warning about conditional
	always being false by inserting preprocessor conditional.  (Thanks
	to Bruce Korb.)

	* __scm.h (SCM_STACK_PTR): New macro. (Cast argument through
	(void *) in order to avoid an aliasing warning; thanks to Bruce
	Korb.)

	* stackchk.h (SCM_STACK_OVERFLOW_P): Use SCM_STACK_PTR.

	* threads.c (suspend, launch_thread, scm_threads_mark_stacks): Use
	SCM_STACK_PTR.

	* threads.c (scm_threads_mark_stacks): Bugfix: Changed
	thread->base --> t->base.

	* eval.c (SCM_CEVAL): Don't cast argument of SCM_STACK_OVERFLOW_P.

2003-05-20  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* deprecated.h, deprecated.c (scm_makstr, scm_makfromstr,
	scm_variable_set_name_hint, scm_builtin_variable,
	scm_internal_with_fluids, scm_make_gsubr,
	scm_make_gsubr_with_generic, scm_create_hook, SCM_LIST0,
	SCM_LIST1, SCM_LIST2, SCM_LIST3, SCM_LIST4, SCM_LIST5, SCM_LIST6,
	SCM_LIST7, SCM_LIST8, SCM_LIST9, scm_listify, scm_sloppy_memq,
	scm_sloppy_memv, scm_sloppy_member, scm_read_and_eval_x,
	scm_subr_entry, SCM_SUBR_DOC, scm_make_subr,
	scm_make_subr_with_generic, scm_make_subr_opt,
	scm_call_catching_errors, scm_make_smob_type_mfpe,
	scm_set_smob_mfpe, scm_strprint_obj, scm_read_0str, scm_eval_0str,
	SCM_CHARS, SCM_UCHARS, SCM_LENGTH): Re-added from the release_1_6
	branch.  Some have been slightly rewritten.
	(scm_i_object_chars, scm_i_object_length): New, to support
	SCM_CHARS, SCM_UCHARS, and SCM_LENTH.
	
2003-05-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (scm_m_do, unmemocopy, SCM_CEVAL):  Reversed order of
	names and inits in the memoized code of do.

2003-05-19  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* c-tokenize.lex (yyget_lineno, yyget_in, yyget_out, yyget_leng,
	yyget_text, yyset_lineno, yyset_in, yyset_out, yyget_debug,
	yyset_debug, yylex_destroy): Added prototypes (otherwise we'll get
	a compilation error if error-on-warning is enabled).

2003-05-17  Marius Vollmer  <mvo@zagadka.de>

	* c-tokenize.lex: Gobble up complete lines after a '#'.  This
	removes preprocessor directives from the snarfage that might
	otherwise confuse us.  These directives appear when compiling with
	"-g3", for example.

2003-05-16  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

	* ChangeLog: add my surname

	* srcprop.c (scm_finish_srcprop): use
	scm_gc_register_collectable_memory()
	(scm_make_srcprops): idem.

2003-05-14  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

	* gc-malloc.c (scm_gc_register_collectable_memory): avoid
	wrap-around for scm_mtrigger
	(scm_gc_register_collectable_memory): abort on overflowing
	scm_mallocated().

2003-05-13  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (xmpz_cmp_d): New macro, handling infs if gmp doesn't.
	(scm_num_eq_p, scm_less_p, scm_max, scm_min): Use it.

2003-05-12  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* backtrace.c (scm_display_error_message): Introduced fancy
	printing with max level 7 and length 10.  (Purpose: avoid printing
	gigantic objects in error messages.)

	* print.c, print.h (scm_i_port_with_print_state): New function.

	* print.c (scm_iprin1, scm_printer_apply,
	scm_port_with_print_state): Use scm_i_port_with_print_state.
	(scm_simple_format): Modified not to destroy print states.
	(print_state_mutex): New mutex.
	(scm_make_print_state, scm_free_print_state, scm_prin1):
	Lock/unlock print_state_mutex.
	
	* deprecated.h (SCM_GC8MARKP, SCM_SETGC8MARK, SCM_CLRGC8MARK):
	Use current names in definitions.

2003-05-10  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_num_eq_p, scm_less_p): Don't pass NaN to mpz_cmp_d.

	* numbers.c (scm_integer_length): On negative bignums, adjust
	mpz_sizeinbase to account for it looking at absolute value where we
	want ones-complement.

	* numbers.c (scm_gcd): In bignum/inum, don't pass yy==0 to mpz_gcd_ui
	since we're only using the ulong return value, and x might not fit.

2003-05-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c, eval.h, read.c, read.h (scm_sym_dot): Moved from eval to
	read.  This will allow to make the definition in read.c static.

2003-05-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c, eval.h, evalext.c, evalext.h (scm_m_undefine): Moved
	from evalext to eval.  This will allow to make some of the
	definitions in eval.c static.

2003-05-06  Kevin Ryde  <user42@zip.com.au>

	* numbers.c (scm_difference): In inum - bignum, handle negative inum.
	(scm_logcount): Use mpz_com, not mpz_neg.

2003-05-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	The purpose of this patch is to make guile's internal memoizers
	distinguishable from memoizing macros created on the scheme level
	or from user provided primitive memoizing macros.  The reason is,
	that the internal memoizers are the only ones that are allowed to
	transform their scheme input into memoizer byte code, while all
	other memoizing macros may only transform scheme code into new
	scheme code.

	To achieve this, a new macro type 'builtin-macro!' is introduced.
	Currently, 'builtin-macro!'s are handled as memoizing macros, but
	this will change when the memoizer and executor are separated.

	* macros.[ch] (scm_i_makbimacro): New.

	* macros.h (SCM_BUILTIN_MACRO_P): New.

	* macros.c (macro_print, scm_macro_type): Support builtin-macro!s.

	* eval.c, goops.c: All of guile's primitive memoizing macros are
	primitive builtin-macros now.

	* eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
	builtin-macros are handled equally to memoizing macros.

2003-05-04  Marius Vollmer  <mvo@zagadka.de>

	* throw.c (scm_ithrow): Remove "asm volatile" hack.  It used to
	work around a bug in GCC 2.95.2 but is now a bug in itself.

2003-05-02  Marius Vollmer  <mvo@zagadka.de>

	* deprecated.h (scm_rstate, scm_rng, SCM_SLOPPY_CONSP,
	SCM_SLOPPY_NCONSP, scm_tc7_ssymbol, scm_tc7_msymbol,
	scm_tcs_symbols): New.

2003-04-30  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* deprecated.h, deprecated.c (scm_protect_object,
	scm_unprotect_object, SCM_SETAND_CAR, SCM_SETOR_CAR,
	SCM_SET_AND_CDR, SCM_SET_OR_CDR, SCM_FREEP, SCM_NFREEP,
	SCM_GC8MARKP, SCM_SETGC8MARK, SCM_CLRGC8MARK, SCM_GCTYP16,
	SCM_GCCDR, scm_remember, scm_the_root_module, scm_make_module,
	scm_ensure_user_module, scm_load_scheme_module, scm_port,
	scm_ptob_descriptor, scm_port_rw_active,
	scm_close_all_ports_except): New.

	* ports.c (scm_c_port_for_each): New function, mostly copied from
	scm_port_for_each.
	(scm_port_for_each): Reimplemented using scm_c_port_for_each.
	* ports.h (scm_c_port_for_each): New prototype.
	
2003-04-28  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* eval.c (scm_m_atdispatch): Removed until actually needed.  (This
	macro was introduced in anticipation of GOOPS method compilation
	code.)

	* goops.c: Removed binding of @dispatch.

2003-04-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
	instructions that bind the macros on the scheme level back to
	goops.c in order to make sure again that the bindings go into the
	(oop goops) module and are not visible from the outside.

2003-04-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c: Non functional change: Separated R5RS and non-R5RS
	macros into different sections of the file and ordered the
	memoizers alphabetically.

2003-04-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (scm_ilookup):  Rewritten to improve readability.

2003-04-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (scm_i_call_closure_0, call_closure_1, call_closure_2):
	Partially reverted patch from 2003-04-23 in oder to find a better
	compromise between readability and debuggability.

2003-04-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c, eval.h, goops.c, goops.h (scm_m_atslot_ref,
	scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and
	definitions of the special goops memoizers from goops.[ch] to
	eval.[ch].  Hmm... it seems that scm_m_atdispatch is not used
	throughout guile.

2003-04-24  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* ports.c, ports.h (scm_i_port_table_mutex): New mutex.

	* ports.c (scm_close_port, scm_flush_all_ports): Ditto.

	* ioext.c (scm_fdes_to_ports): Ditto.

	* vports.c (scm_make_soft_port): Changed SCM_DEFER/ALLOW_INTS into
	lock/unlock scm_i_port_table_mutex.

	* strports.c (scm_mkstrport): Ditto.

	* ports.c (scm_void_port, scm_port_for_each): Ditto.

	* fports.c (scm_fdes_to_port): Ditto.

2003-04-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	This set of patches contains no functional changes, only debatable
	minor stylistic ones.  Still, in order to prepare a patch between
	my local copy and the CVS version, I decided to submit the changes
	below.  Then, the patch will hopefully only contain relevant
	modifications :-)

	* eval.c (iqq): Added const specifier.

	* eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
	Use NULL instead of 0 to indicate that a pointer is returned.
	Removed some misleading 'fall through' comments.

	* eval.c (scm_i_call_closure_0, call_closure_1, call_closure_2):
	Split up long expressions into smaller ones to be more debugging
	friendly.

2003-04-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.h (SCM_ENTER_FRAME_HDLR, SCM_APPLY_FRAME_HDLR,
	SCM_EXIT_FRAME_HDLR): Use SCM_PACK to convert data to a SCM value
	rather than casting to SCM.

2003-04-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* sort.c, pairs.h: Removed unnecessary includes.

2003-04-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* sort.c: Replaced hand-made trampline code by the new official
	mechanism from eval.c.  This fixes a segfault in the new test file
	sort.test.

	(quicksort, compare_function, scm_restricted_vector_sort_x,
	scm_sorted_p, scm_merge, scm_merge_list_x, scm_merge_x,
	scm_merge_list_step, scm_sort_x, scm_sort, scm_merge_vector_x,
	scm_merge_vector_step, scm_stable_sort_x, scm_stable_sort,
	scm_sort_list_x, scm_sort_list): Use trampoline mechanism from
	eval.c.

	(subr2less, lsubrless, closureless, applyless, scm_cmp_function,
	cmp_fun_t): Removed.

	(compare_function): Added.

	* sort.c (quicksort, SWAP, stack_node): Replaced pointer
	arithmetics with index arithmetics.  Changed quicksort to work on
	an array of SCM values instead of an array of characters.  Avoid
	bytewise copying of SCM elements.  Avoid allocating memory on the
	stack with alloca.  Fixed some comments.

2003-04-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (EXTEND_ENV): Eliminated.

	(unmemocopy, SCM_CEVAL, SCM_APPLY): Use SCM_EXTEND_ENV instead of
	EXTEND_ENV.

2003-04-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* __scm.h (SCM_DEBUG_DEBUGGER_SUPPORT): New compile-time option.

	* gc.card.c (scm_gc_marked_p): Fixed compiler warning when
	compiling with SCM_DEBUG==1 by moving definition behind prototype.

	* gc.card.c (scm_dbg_t_list_cell, scm_dbg_t_double_cell,
	scm_dbg_gc_marked_p, scm_dbg_gc_get_card, scm_dbg_gc_get_bvec,
	scm_t_list_cell_struct, scm_t_list_cell, scm_t_double_cell,
	scm_gc_marked_p, scm_gc_get_card, scm_gc_get_bvec): Fixed
	functions such that they check if the object is a non-immediate.
	Further, renamed identifiers to use the scm_dbg_ prefix and made
	their inclusion into the lib dependent of the
	SCM_DEBUG_DEBUGGER_SUPPORT compile time option.

2003-04-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* __scm.h: Fixed comment about the SCM_DEBUG_TYPING_STRICTNESS
	debug option.

2003-04-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* list.c (scm_ilength, scm_last_pair), unif.c (l2ra): Prefer
	!SCM_CONSP over SCM_NCONSP.  Now, guile itself does not include
	any calls to SCM_NCONSP any more.

	* unif.c (l2ra): Eliminate redundant check.

2003-04-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* list.c (scm_cons_star), ramap.c (scm_ra_sum, scm_ra_product,
	scm_array_map_x), unif.c (l2ra): Prefer !SCM_NULLP over
	SCM_NNULLP.  Now, guile itself does not include any calls to
	SCM_NNULLP any more.

2003-04-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (unmemocopy, SCM_APPLY, scm_map, scm_for_each,
	scm_copy_tree): Place assignment expressions which are part of
	other expressions into an expression of their own.

2003-04-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* goops.c (TEST_CHANGE_CLASS, scm_sys_initialize_object): Don't
	compare SCM values with !=.

2003-04-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c, eval.h, evalext.c, evalext.h (scm_sym_setter,
	scm_m_generalized_set_x, scm_init_evalext): Move the declaration
	and definition of the memoizer for the generalized set! macro from
	evalext.[ch] to eval.[ch].  Use the SCM_SYNTAX snarfer macro to
	define the macro object.

	* eval.c, eval.h (s_set_x, scm_s_set_x, scm_m_set_x,
	scm_m_generalized_set_x): Since now scm_s_set_x is only used in
	eval.c, it is made static and renamed to s_set_x.

	* evalext.c (scm_defined_p, scm_m_undefine): Prefer !SCM_<foo>
	over SCM_N<foo>.

2003-04-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c, root.h (scm_undefineds, SCM_NUM_PROTECTS, undefineds,
	scm_init_eval): Made scm_undefineds static in eval.c, renamed it
	to undefineds and registered the object as a permanent object.

	* eval.c, eval.h (scm_f_apply, scm_init_eval): Made scm_f_apply
	static in eval.c, renamed it to f_apply and registered the object
	as a permanent object.

2003-04-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* eval.c (SCM_BIT7, SCM_BIT8, unmemocopy, SCM_CEVAL): Renamed
	file-local macro SCM_BIT8 to SCM_BIT7, which is more appropriate.

2003-04-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* numbers.c (scm_logtest):  Fixed argument bug in the call to
	mpz_and, which showed up when compiling with SCM_DEBUG defined.

2003-04-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	we're sure to pick up any critical defines like _GNU_SOURCE early.
	#include <limits.h> removed in favor of scmconfig.h inclusion when
	appropriate.  STDC_HEADERS based inclusion of stdlib.h,
	sys/types.h, stddef.h, and sys/stdtypes.h removed in favor of
	scmconfig.h inclusion when appropriate.  Various Win32 related
	definitions removed in favor of scmconfig.h inclusion when
	appropriate.
	(HAVE_UINTPTR_T): definition removed (see NEWS).
	(SIZEOF_PTRDIFF_T): definition removed (see NEWS).
	(HAVE_LONG_LONGS): definition removed (see NEWS).
	(HAVE_LONG_LONG): definition removed (see NEWS).
	(HAVE_PTRDIFF_T): definition removed (see NEWS).

	* Makefile.am: scmconfig.h is now generated by building and
	running gen-scmconfig.h and capturing its output.  gen-scmconfig
	uses config.h and the configure.in generated gen-scmconfig.h to
	decide what to output.  See gen-scmconfig.c for details.
	(noinst_PROGRAMS): add gen-scmconfig.
	(gen_scmconfig_SOURCES): new variable.
	(gen-scmconfig.$(OBJEXT)): new target - be careful to handle
	cross-compiling right.
	(scmconfig.h): build scmconfig.h from gen-scmconfig's output.
	(BUILT_SOURCES): add scmconfig.h.

2003-03-19  Marius Vollmer  <mvo@zagadka.de>

	* gc_os_dep.c: Added defines for sparc-unknown-netbsdelf1.5 from
	Adrian Bunk.  Thanks!

2003-03-19  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* goops.c (make_class_from_template): New fourth arg:
	applicablep.
	(scm_class_extended_generic_with_setter, scm_class_self): Fixed
	cpls.

	* smob.c (scm_set_smob_apply): Call scm_i_inherit_applicable.

	* goops.c, objects.c, objects.h (scm_make_extended_class): New
	second arg: applicablep.
	(scm_i_inherit_applicable): New function.

	* goops.c, goops.h (scm_class_applicable,
	scm_class_extended_accessor): New classes.

2003-03-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* procs.c (scm_procedure_documentation): Removed redundant
	SCM_NIMP test and replaced other calls to SCM_IMP by more explicit
	predicates.

2003-03-11  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* list.c, list.h (scm_filter, scm_filter_x): New functions.

	* modules.c (scm_module_import_interface): New function.

	* goops.c, goops.h (scm_class_accessor_method): Renamed from
	scm_class_accessor.
	(scm_class_accessor): New class.

2003-03-06  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* goops.c (scm_primitive_generic_generic): Enable primitive
	generic if not enabled.
	(scm_sys_goops_loaded): Setup unextended primitive generics.

	* goops.c, goops.h (scm_c_extend_primitive_generic): New function.

	* snarf.h (SCM_PRIMITIVE_GENERIC, SCM_PRIMITIVE_GENERIC_1): New
	snarf macros.

	* numbers.c (scm_abs): Use SCM_PRIMITIVE_GENERIC.  (This is only a
	testing example.  All uses of SCM_GPROC should be converted.)

	* procprop.c (scm_stand_in_scm_proc): Use scm_assq instead of
	scm_assoc.

	* eq.c (scm_equal_p): Turned into a primitive generic.

2003-02-27  Rob Browning  <rlb@defaultvalue.org>

	* Makefile.am (scmconfig.h): new target -- generate file from
	../config.h.
	(modinclude_HEADERS): remove version.h.
	(nodist_modinclude_HEADERS): add version.h.

2003-02-24  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	This fixes a serious GC bug, introduced during the latest
	reorganization of the GC, which disabled freeing of structs and
	GOOPS objects:

	* struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to
	SCM_EOL.
	(scm_struct_prehistory): Move scm_free_structs to
	scm_before_mark_c_hook.

	* gc-card.c (sweep_card): Check that we haven't swept structs on
	this card before.  That can happen if scm_i_sweep_all_segments has
	been called from some other place than scm_igc.

2003-02-19  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* environments.c (DEFAULT_OBARRAY_SIZE): Changed from 137 to 31
	(since hash tables now adapt their size).

	* modules.c (scm_modules_prehistory): Changed from 2001 to 1533
	(current number of prehistory bindings; hashtable code will select
	a prime which is greater than this value).

	* symbols.c (scm_symbols_prehistory): Changed from 1009 to 2139
	(current number of initial symbols).

	* properties.c (scm_init_properties): Don't specify size of
	scm_properties_whash.

	* objprop.c (scm_init_objprop): Don't specify size of
	scm_object_whash.

	* keywords.c (scm_init_keywords): Don't specify a hash table size.

	* hooks.c (scm_c_hook_add): Fixed bug in append mode.

	The following changes introduce the use of resizable hash tables
	throughout Guile.  It also renames the old *-hash-table* functions
	to *-alist-vector* and places them, together with the rest of the
	weak vector support, in the module (ice-9 weak-vector).  We should
	probably introduce a new, better, API for weak references, for
	example "weak pairs" a la MIT-Scheme.  (In Chez scheme, they even
	look like and are used like ordinary pairs.)

	* environments.c (obarray_enter, obarray_retrieve, obarray_remove,
	leaf_environment_fold, obarray_remove_all): Use hashtable
	accessors.

	* gc.c (scm_init_storage): Moved hook initialization to
	scm_storage_prehistory.
	(scm_storage_prehistory): New function.
	(scm_igc): Added commentary about placement of
	scm_after_sweep_c_hook.

	* gc-mark.c (scm_mark_all): Use hashtable accessors.
	(scm_gc_mark_dependencies): Use SCM_WVECT_WEAK_KEY_P and
	SCM_WVECT_WEAK_VALUE_P.

	* hashtab.c, hashtab.h (scm_hash_for_each, scm_hash_map): New
	functions.
	(scm_vector_to_hash_table, scm_c_make_resizing_hash_table):
	Removed.
	(scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
	scm_make_doubly_weak_hash_table): Moved here from weaks.c.

	* init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added
	calls to scm_storage_prehistory and scm_hashtab_prehistory.

	* modules.c (module-reverse-lookup): Use hashtable accessors.

	* symbols.c, symbols.h (scm_i_hash_symbol): New function.

	* weaks.c, weaks.h (scm_make_weak_key_alist_vector,
	scm_make_weak_value_alist_vector,
	scm_make_doubly_weak_alist_vector): New functions.

	* weaks.c (scm_init_weaks_builtins): New function.

	* weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE,
	SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
	SCM_WVECT_NOSCAN_P): New macros.

	* weaks.c (scm_scan_weak_vectors):  Use SCM_WVECT_WEAK_KEY_P
	and SCM_WVECT_WEAK_VALUE_P.

	* weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from
	allocate_weak_vector and exported.

2003-02-13  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* hashtab.c: Undid thread safety.  (We decided that it's better to
	let the user explicitly protect the tables (or not) according what
	is suitable for the application.)

2003-02-12  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made
	thread safe and handle resizing tables.
	(scm_ihashx, scm_sloppy_assx, scm_delx_x): Removed
	SCM_DEFER/ALLOW_INTS.

2003-02-11  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* hashtab.c (scm_vector_to_hash_table,
	scm_c_make_resizing_hash_table, scm_make_hash_table): New
	functions.
	(scm_hash_fn_get_handle, scm_hash_fn_create_handle_x): Made thread
	safe and handle resizing tables.

	* weaks.c (scm_make_weak_key_hash_table,
	scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
	Size argument made optional.  Return resizable table if not
	specified.

2003-02-10  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
	Fixed formals tests for closures.  (Thanks to Kevin Ryde.)

2003-02-05  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* debug.c (scm_procedure_source): Handle all objects for which
	procedure? is #t.  (Thanks to Bill Schottstaedt.)

2003-01-23  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* futures.c (mark_futures): Don't need to mark data of recycled
	futures.
	(scan_futures, cleanup_undead): Be smarter about marking
	futures---avoid unnecessary passes through future lists.

	* futures.h, futures.c: New files; Introduced recycling of
	futures.  For fine-grained threading this lifts performance to
	another level.  We can now use parallelization in inner loops of
	Guile programs without impossible overhead.

	* threads.h, threads.c: Moved futures to their own file.

	* Makefile.am (libguile_la_SOURCES): Added futures.c.
	(DOT_X_FILES): Added futures.x.
	(DOT_DOC_FILES): Added futures.doc.
	(modinclude_HEADERS): Added futures.h.

	* threads.c, threads.h (scm_i_create_thread): Renamed from
	create_thread and made global.

	* futures.c (scm_make_future): New procedure.

	* eval.c: #include "libguile/futures.h".

	* init.c: #include "futures.h"
	(scm_init_guile_1): Call scm_init_futures.

	* stime.c (SCM_TIME_UNITS_PER_SECOND): Renamed from CLKTCK.

	* stime.h (SCM_TIME_UNITS_PER_SECOND): Definition moved here.

	* eval.c, eval.h (scm_trampoline_0, scm_i_call_closure_0): New
	functions.

	* eval.c (scm_trampoline_1): Fixed arguments test for closures.

2003-01-22  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* threads.c (create_thread): Don't unwind dynwind chain of parent
	thread before creation.  Just start the new thread with an empty
	dynwind chain.

2003-01-20  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* evalext.c, evalext.h (scm_self_evaluating_p): New function.

2003-01-10  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* threads.c (scm_timed_wait_condition_variable): Support timed
	waiting also for simple condition variables.

	* goops.c (TEST_CHANGE_CLASS): Use scm_change_object_class instead
	of calling the procedure change-object-class.

2003-01-09  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* ramap.c (scm_ramapc): Typo in error message.

2003-01-08  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* goops.c (scm_sys_prep_layout_x): Bugfix: Only create layout for
	slots with instance allocation.
	
	* goops.c, goops.h (scm_class_extended_generic_with_setter): New
	class.
	(scm_compute_applicable_methods): Use scm_generic_function_methods.

	* goops.c (scm_generic_function_methods): Support extended
	generic functions.

2002-12-29  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* eval.c (unmemocopy): Bugfix: scm_sym_delay --> scm_sym_future.
	Thanks to Neil for pointing this out!

2002-12-29  Neil Jerram  <neil@ossau.uklinux.net>

	* lang.h: Remove declarations matching definitions removed from
	lang.c (just below).

2002-12-28  Neil Jerram  <neil@ossau.uklinux.net>

	* lang.c (scm_nil_cons, scm_nil_car, scm_nil_cdr, scm_null,
	scm_m_while, scm_nil_eq): Remove definitions that were superfluous
	and already commented out.

	* read.h (scm_lreadparen), read.c (scm_lreadr, scm_read_token,
	scm_lreadparen): Support reading vectors with Elisp syntax if
	SCM_ELISP_READ_EXTENSIONS is defined.  (SCM_ELISP_READ_EXTENSIONS
	is not currently defined, and there isn't even a configure switch
	to enable it yet.)

2002-12-26  Marius Vollmer  <mvo@zagadka.ping.de>

	* Makefile.am (c-tokenize.o): Refer to source via $< so that vpath
	builds work.
	(EXTRA_DIST): Added version.h.in.
	
2002-12-21  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	This change makes it possible for one thread to do lazy sweeping
	while other threads are running.  Now only the mark phase need to
	have all threads asleep.  We should look further into this issue.
	Presently, I've put the locking of scm_i_sweep_mutex at
	"conservative" places due to my current lack of knowledge about
	the garbage collector.  Please feel free to restrict these regions
	further to allow for maximal parallelism!

	* gc.c, gc.h (scm_i_sweep_mutex): New mutex.

	* gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
	scm_gc_register_collectable_memory): Substitute locking of
	scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
	(scm_igc): Lock sweep mutex here instead of in callers; Calls to
	scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
	the single-thread section (which now only contains the mark
	phase).
	(scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
	Removed SCM_DEFER/ALLOW_INTS.  Simply call scm_igc directly.

	* threads.c (gc_section_mutex): Removed.

2002-12-19  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* threads.c (create_thread): Clear parent field in root state in
	order not to unnecessarily remember dead threads.

	* eval.c (call_subr2o_1, call_lsubr2_2): New functions.
	(scm_trampoline_1, scm_trampoline_2): Use them.

2002-12-18  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	Partial introduction of real plugin interface.

	* Makefile.am (modinclude_HEADERS): Added threads-plugin.h.
	(EXTRA_DIST): Added threads-plugin.c.

	* threads-plugin.h, threads-plugin.c: New files.

	* threads.h: #include "libguile/threads-plugin.h".

	* threads.c: #include "libguile/threads-plugin.c".

	* pthread-threads.c: Temporarily remove debugging functions.

	* threads.c, threads.h (scm_yield): Added back.

2002-12-18  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* threads.c (really_launch): Detach before unlocking
	thread_admin_mutex in order not to risk being joined.
	(scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep
	thread_admin_mutex locked during GC.

	* pthread-threads.c, pthread-threads.h: Improvements to debugging
	functions.

2002-12-16  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): Added
	support for debugging mutex operations.

	* threads.c (scm_thread): Removed filed joining_threads.
	(thread_print): Print thread number as well as address of thread
	structure.
	(scm_join_thread): Bugfix.
	(scm_lock_mutex, scm_try_mutex, scm_unlock_mutex,
	scm_timed_wait_condition_variable, scm_signal_condition_variable,
	scm_broadcast_condition_variable): Use the low-level API.
	(scm_all_threads): Return copy of thread list (to prevent
	unintended destruction).
	(scm_threads_prehistory): Initialize heap_mutex of fake thread.

	* pthread-threads.c, pthread-threads.h, threads.c: Fixes to
	pthread "native" recursive mutex support.

2002-12-15  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions.
	Simply lock a thread C API recursive mutex.
	(SCM_NONREC_CRITICAL_SECTION_START,
	SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
	SCM_REC_CRITICAL_SECTION_END): Removed.

	* eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
	direct calls to scm_rec_mutex_lock / unlock around the three calls
	to scm_m_expand_body.

	* eval.c, eval.h (promise_free): New function.
	(scm_force): Rewritten;  Now thread-safe; Removed
	SCM_DEFER/ALLOW_INTS.

	* pthread-threads.h: Added partially implemented plugin interface
	for recursive mutexes.  These are, for now, only intended to be
	used internally within the Guile implementation.

	* pthread-threads.c: New file.

	* threads.c: Conditionally #include "pthread-threads.c".

	* eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
	thread-safe;

	* snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
	SCM_GLOBAL_REC_MUTEX): New macros.

	* eval.c, threads.c, threads.h, snarf.h: Rewrote critical section
	macros---use mutexes instead.

	* tags.h (SCM_IM_FUTURE): New tag.

	* eval.c (scm_m_future): New primitive macro.
	(SCM_CEVAL): Support futures.
	(unmemocopy): Support unmemoization of futures.

	* print.c (scm_isymnames): Name of future isym.

	* version.c: Unmade some changes to my private copy that got
	committed by mistake.

2002-12-11  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* gc-malloc.c, gc.h, init.c: Reverted gc-malloc change of
	2002-12-10.

	* gc.c (scm_igc): Don't call scm_i_thread_invalidate_freelists.

	* gc.c (scm_gc_sweep): Call it here instead, which is a more
	logical place.

	* threads.c (create_thread): Remember root object until the handle
	of the new thread is on all_threads list.

	* root.c (scm_make_root): Moved copying of fluids until after
	creation of root handle so that the fluids are GC protected.  Also
	removed the critical section.

2002-12-10  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* gc-malloc.c, gc.h (scm_gc_malloc_prehistory): New function.

	* gc-malloc.c (malloc_mutex): New mutex.
	(scm_gc_malloc_prehistory): Initialize it.
	(scm_realloc): Serialize call to realloc
	(scm_calloc): Same for calloc.
	Thanks to Wolfgang Jaehrling!
	(Now we have to make sure all calls to malloc/realloc are made
	through scm_malloc.)

	* init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory.

	* threads.c (really_launch): Release heap (to prevent deadlock).
	(create_thread): Release heap before locking thread admin mutex.

2002-12-10  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* threads.c (scm_i_thread_invalidate_freelists): New
	function.

	* gc.c (scm_igc): Call scm_i_thread_invalidate_freelists.

	* modules.c (scm_export): Inserted a return statement.

2002-12-10  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

	* modules.c (scm_export): new function

	* gc-card.c: add a note about malloc()/free() overhead.

2002-12-10  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* Makefile.am (c-tokenize.$(OBJEXT)): Don't look for c-tokenize.c
	in srcdir.

2002-12-10  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	These changes remove scm_ints_disabled (which hasn't has any
	effect in Guile for quite some time).
	
	* async.c, error.h (scm_ints_disabled): Removed.

	* gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1),
	root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK,
	SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled.
	(old_ints): Removed.

	* __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
	critical section.
	(SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
	SCM_ALLOW_INTS.

2002-12-09  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait):
	Removed accidental #if 0 around these functions.

	These changes are the start of support for preemptive
	multithreading.  Marius and I have agreed that I commit this code
	into the repository although it isn't thoroughly tested and surely
	introduces many bugs.  The bugs should only be exposed when using
	threads, though.  Signalling and error handling for threads is
	very likely broken.  Work on making the implementation cleaner and
	more efficient is needed.
	
	* __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
	(SCM_NONREC_CRITICAL_SECTION_START,
	SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
	SCM_REC_CRITICAL_SECTION_END): New macros.
	(SCM_CRITICAL_SECTION_START/END): Defined here.

	* eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
	the three calls to scm_m_expand_body.

	* gc.h: #include "libguile/pthread-threads.h";
	(SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.

	* gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
	scm_t_key;

	* gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
	access.

	* gc-freelist.c (scm_gc_init_freelist): Create freelist keys.

	* gc-freelist.c, threads.c (really_launch): Use
	SCM_FREELIST_CREATE.

	* gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):

	* gc.c (scm_i_expensive_validation_check, scm_gc,
	scm_gc_for_newcell): Put threads to sleep before doing GC-related
	heap administration so that those pieces of code are executed
	single-threaded.  We might consider rewriting these code sections
	in terms of a "call_gc_code_singly_threaded" construct instead of
	calling the pair of scm_i_thread_put_to_sleep () and
	scm_i_thread_wake_up ().  Also, we would want to have as many of
	these sections eleminated.

	* init.c (scm_init_guile_1): Call scm_threads_prehistory.

	* inline.h: #include "libguile/threads.h"

	* pthread-threads.h: Macros now conform more closely to the
	pthreads interface.  Some of them now take a second argument.

	* threads.c, threads.h: Many changes.

2002-12-09  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* Makefile.am (version.h): Changed $^ --> $< in rule for
	version.h.
	
2002-12-08  Rob Browning  <rlb@defaultvalue.org>

	* version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
	(SCM_MINOR_VERSION): use @--@ substitution now.
	(SCM_MICRO_VERSION): use @--@ substitution now.
	(scm_effective_version): new function prototype.

	* version.c (scm_effective_version): new function, also add
	effective-version.

	* Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
	(libpath.h): use GUILE_EFFECTIVE_VERSION to compute
	SCM_LIBRARY_DIR.
	(version.h): generate this here rather than configure.in.  This
	approach tracks source edits better (i.e. more immediately).
	Might be worth considering for other .in files too.

2002-12-02  Marius Vollmer  <mvo@zagadka.ping.de>

	Reorganized thread package selection.  A thread package now only
	implements a small set of pthread like functions and Guile
	implements the rest on top of that.  Guile's implementation is
	what the "coop-pthreads" package has been previously.  Support for
	"coop" threads has been removed until I get time to add it again.

2002-12-01  Mikael Djurfeldt  <mdj@linnaeus>

	The following change makes it possible to move procedure
	application dispatch outside inner loops.  The motivation was
	clean implementation of efficient replacements of R5RS primitives
	in SRFI-1.

	The semantics is clear: scm_trampoline_N returns an optimized
	version of scm_call_N (or NULL if the procedure isn't applicable
	on N args).

	Applying the optimization to map and for-each increases efficiency
	noticeably.  For example, (map abs ls) is 8 times faster than
	before.

	* eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.

	* eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.

	* eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
	(map, for-each): Handle also application on two args as a special
	case; Use trampolines.

	Other changes:
	
	* sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
	(subr2oless): Removed.
	(scm_restricted_vector_sort_x): Use scm_return_first to keep the
	vector GC protected.

	* eval.c (check_map_args): Use scm_out_of_range_pos instead of
	scm_out_of_range.

	* coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
	part of the API, otherwise it's difficult to write Guile

	"libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.

	* coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex -->
	s_unlock_mutex.

2002-11-10  Marius Vollmer  <mvo@zagadka.ping.de>

	defined when HAVE_RESTARTABLE_SYSCALLS is not defined.
	(HAVE_RESTARTABLE_SYSCALLS): Do not define when USE_COPT_THREADS
	is defined.

2002-10-27  Marius Vollmer  <mvo@zagadka.ping.de>
