2001-07-04  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* hooks.c (scm_make_hook, scm_add_hook_x),
	(scm_remove_hook_x, scm_reset_hook_x, scm_run_hook): Added return
	value info to the docstrings.

2001-07-03  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

2001-07-01  Marius Vollmer  <mvo@zagadka.ping.de>

	* strports.c (scm_read_0str, scm_eval_0str): Call
	scm_c_read_string and scm_c_eval_string respectively, not
	themselves.  Thanks to Dale P. Smith!

2001-06-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* unif.c (scm_array_set_x):  The variable args does not
	necessarily have to be a list.  Further, got rid of a redundant
	SCM_NIMP test.

2001-06-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* list.c (SCM_I_CONS):  Make sure the cell type is initialized
	last.

	* gc.c (s_scm_map_free_list, scm_igc, scm_gc_sweep,
	init_heap_seg): Fixed signedness.

	(init_heap_seg):  Replaced strange for-loop with a while loop.

	* weaks.h (WEAKSH, SCM_WEAKS_H):  Rename <foo>H to SCM_<foo>_H.

	(SCM_WVECTP):  Prefer !SCM_<pred> over SCM_N<pred>.

	The following patch adds conservative marking for the elements of
	free or allocated cells.

	* gc.c (allocated_mark, heap_segment):  New static functions.

	(which_seg):  Deleted, since the functionality is now provided by
	function heap_segment.

	(map_free_list):  Use heap_segment instead of which_seg.

	(MARK):  If cell debugging is disabled, mark free cells
	conservatively.

	(scm_mark_locations, scm_cellp):  Extracted the search for the
	heap segment of a SCM value into function heap_segment.

	(scm_init_storage):  Allocated cells must be marked
	conservatively.

	* gc.[ch] (scm_gc_mark_cell_conservatively):  New function.

	The following patch changes the representation of weak vectors to
	double cells instead of using an extension of the vector's
	allocated memory.

	* gc.c (MARK):  Use SCM_SET_WVECT_GC_CHAIN instead of assigning to
	the result of SCM_WVECT_GC_CHAIN.

	(scm_gc_sweep):  Weak vectors don't have extra fields any more.

	* weaks.c (allocate_weak_vector):  New static function.  It does
	not patch any previously created vector object during the
	construction of a weak vector, and thus doesn't need to switch
	off interrupts during vector creation.

	(scm_make_weak_vector, scm_make_weak_key_hash_table,
	scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
	Use allocate_weak_vector to provide the new weak vector object.

	* weaks.h (SCM_WVECT_TYPE, SCM_SET_WVECT_TYPE,
	SCM_SET_WVECT_GC_CHAIN):  New macros.  The weak vector subtype is
	now stored in the double cell.

	(SCM_IS_WHVEC, SCM_IS_WHVEC_V, SCM_IS_WHVEC_B, SCM_IS_WHVEC_ANY):
	Use SCM_WVECT_TYPE.

	(SCM_WVECT_GC_CHAIN):  The weak objects are now chained together
	using an entry of the double cell.

2001-06-30  Thien-Thi Nguyen  <ttn@revel.glug.org>

	* stamp-h.in: bye bye

2001-06-30  Marius Vollmer  <mvo@zagadka.ping.de>

	* gh_eval.c (gh_eval_str): Use scm_c_eval_string instead of
	scm_eval_0str.

	* load.c, load.h (scm_c_primitive_load,
	scm_c_primitive_load_path): New.

	* strports.c, strports.h (scm_c_read_string): Renamed from
	scm_read_0str.  Also, added "const" qualifier to argument.
	(scm_c_eval_string): Renamed from scm_eval_0str.
	(scm_read_0str, scm_eval_0str): Deprecated.

2001-06-28  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* fluids.c (scm_c_with_fluid): Use scm_list_1() instead of
	SCM_LIST1.

2001-06-28  Keisuke Nishida  <kxn30@po.cwru.edu>

	* list.h (scm_list_1, scm_list_2, scm_list_3, scm_list_4, scm_list_5,
	scm_list_n): New functions.
	(SCM_LIST0, SCM_LIST1, SCM_LIST2, SCM_LIST3, SCM_LIST4, SCM_LIST5,
	SCM_LIST6, SCM_LIST7, SCM_LIST8, SCM_LIST9, scm_listify): Deprecated.
	(lots of files): Use the new functions.

	* goops.c (CALL_GF1, CALL_GF2, CALL_GF3, CALL_GF4): Use scm_call_N.

	* strings.c: #include "libguile/deprecation.h".

2001-06-27  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* read.c (scm_lreadr): When reading a hash token, check for a
	user-defined hash procedure first, so that overriding the builtin
	hash characters is possible (this was needed for implementing
	SRFI-4's read synax `f32(...)').

	* num2integral.i.c: Use scm_t_signed_bits instead of scm_t_bits,
	because the latter is unsigned now and breaks comparisons like
	(n < (scm_t_signed_bits)MIN_VALUE).

2001-06-26  Neil Jerram  <neil@ossau.uklinux.net>

	* eval.h, eval.c (scm_call_4): New function.

	* eval.c (SCM_APPLY, SCM_CEVAL, ENTER_APPLY): Call trap handlers
	directly rather than dispatching to them via scm_ithrow and a lazy
	catch.

	* eval.c (scm_evaluator_trap_table), eval.h (SCM_ENTER_FRAME_HDLR,
	SCM_APPLY_FRAME_HDLR, SCM_EXIT_FRAME_HDLR): Add three new options
	for trap handler procedures.

	* debug.h (SCM_RESET_DEBUG_MODE): Add checks for trap handler
	procedures not being #f.

2001-06-27  Michael Livshin  <mlivshin@bigfoot.com>

	* Makefile.am (c-tokenize.c): add rule to generate it.
	(EXTRA_DIST): add c-tokenize.lex, so it gets distributed.

	filter-doc-snarfage.c: remove.

2001-06-26  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* ports.c (scm_output_port_p): Use result of SCM_COERCE_OUTPORT.

	The following set of changes makes compiling Guile under various
	Windows compilers easier.  Compilation under GNU systems should
	not be affected at all.

	Thanks to Stefan Jahn for all necessary information, patches and
	testing.

	* posix.c: Conditialize getpwent, getgrent, kill, getppid, getuid,
	getpgrp, ttyname, primitive-fork and some header inclusion for
	Windows.

	* random.c: Define M_PI, if not predefined and use __int64 for
	LONG64 under Windows.

	* scmsigs.c: Emulate some functions (alarm, sleep, kill) under
	Windows and conditionalize some signal names.

	* socket.c (scm_getsockopt): Added missing comma.
	Include socket library header under Windows.

	* stime.c (CLKTCK): Add cast to int, to make it compile under
	Windows.

	* ports.c (truncate): New function, compiled only under Windows.

	* net_db.c: Do not declare errno under Windows.

	* iselect.h, inet_aton.c: Include socket library headers under
	Windows.

	* guile.c (inner_main): Under Windows, initialize socket library
	and initialize gdb_interface data structures.

	* gdb_interface.h: Under Windows, gdb_interface cannot be
	initialized statically.  Initialize at runtime instead.

	* fports.c (write_all): ssize_t -> size_t.
	(fport_print): Conditionalize call to ttyname().
	(getflags): New function, compiled only under Windows.

	* filesys.c: Conditionalize inclusion of <pwd.h>.  Conditionalize
	primitives chown, link, fcntl.
	(scm_basename, scm_dirname): Under Windows, handle \ as well as /
	as path seperator.

	* backtrace.c: Include <io.h> under Windows.

	* async.h (ASYNCH, SCM_ASYNC_H): Rename <foo>H to SCM_<foo>_H.

	* _scm.h: Added preprocessor conditional for __MINGW32__ for errno
	declaration.

	scm_apply_0, scm_apply_1, scm_apply_2, scm_apply_3): New functions.
	* eval.h (scm_call_0, scm_call_1, scm_call_2, scm_call_3,

	* goops.c, hashtab.c, scmsigs.c, sort.c: #include "libguile/root.h".

2001-06-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* filesys.c (scm_close), ports.c (scm_close_port,
	scm_port_closed_p), strop.c (scm_string_null_p):  Use SCM_BOOL
	instead of SCM_NEGATE_BOOL.

	* filesys.c (scm_stat):  Clean up type dispatch.

	* filesys.c (scm_stat), ports.c (scm_input_port_p,
	scm_output_port_p):  Get rid of redundant IM type check.

	* filesys.c (scm_readdir, scm_getcwd, scm_readlink), gh_data.c
	(gh_str2scm), load.c (scm_primitive_load, scm_internal_parse_path,
	scm_search_path), net_db.c (scm_gethost, scm_getnet, scm_getproto,
	scm_return_entry), numbers.c (scm_number_to_string), objects.c
	(scm_make_subclass_object), ports.c (scm_port_mode), read.c

	scm_string_split), strports.c (scm_strport_to_string), symbols.c
	(scm_symbol_to_string), vports.c (sf_write):  Use scm_mem2string
	instead of scm_makfromstr.

	* net_db.c (scm_sethost, scm_setnet, scm_setproto, scm_setserv),
	ports.c (scm_close_all_ports_except), read.c (scm_lreadr,
	scm_read_hash_extend), stime.c (scm_strftime), strings.c

	SCM_<foo>_H.

	* validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY):  Eliminate
	warning about comparing signed and unsigned values.  This fix is
	not optimal, since it won't work reliably if sizeof (c_start) >
	sizeof (size_t) or sizeof (c_end) > sizeof (size_t).  A better
	solution is to define this macro as an inline function, thus
	allowing to specifiy the types of c_start and c_end.

	* stacks.c (NEXT_FRAME, narrow_stack):  Prefer explicit type check
	over SCM_N?IMP, !SCM_<pred> over SCM_N<pred>.

	(narrow_stack):  Make i unsigned.  Don't use side-effecting
	operations in conditions.

	(narrow_stack, scm_make_stack, scm_stack_id,
	scm_last_stack_frame):  Get rid of redundant SCM_N?IMP checks.

	(scm_make_stack, scm_stack_id, scm_last_stack_frame):  Clean up
	type dispatch.  No need to cast result of SCM_DEBUGOBJ_FRAME any
	more.

	(scm_stack_ref, scm_frame_previous, scm_frame_next):  Fix
	signedness.
