+2004-06-15 Rob Browning <rlb@defaultvalue.org>
+
+ * script.c (scm_shell_usage): minor phrasing change.
+
+ * gc_os_dep.c: update ifdefery for macosx.
+ (scm_get_stack_base): separate result initialization from
+ declaration to slience warnings with macosx and hp-ux using gcc
+ 3.3. Thanks to Andreas Vögele.
+
+2004-06-13 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.
+
+2004-06-06 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * list.[ch] (scm_i_finite_list_copy): New internal function to
+ copy lists that are known to be finite (though not necessarily
+ proper).
+
+ * debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
+ a closure's argument list like an expression of a body.
+
+ * eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
+ unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
+ unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,

+ unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
+ unmemoize_builtin_macro): New static functions and symbols.
+
+ (scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy
+ now has a slightly different meaning: The memoized form that is
+ receives as its argument is now interpreted as a sequence of
+ expressions from a body.
+
+ (unmemocar, scm_unmemocar): Since the whole functionality of
+ unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
+ has its old content back and is deprecated, while unmemocar has
+ been removed.
+
+ (SCM_BIT7): Removed.
+
+ (CEVAL): For unmemoizing a single expression, call
+ unmemoize_expression instead of scm_unmemocopy, which now expects
+ a sequence of body expressions. Eliminated unnecessary empty
+ environment frame when executing let* forms. Eliminated
+ unmemoization step from evaluator.
+
+2004-06-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>
+
+ * eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
+ macroexp and made static. Added new version of scm_macroexp that
+ emits a deprecation warning and then calls macroexp.
+ (scm_m_undefine): Issue deprecation warning.
+
+2004-05-30 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
+ Modified to make set! work on symbols that represent syntactic
+ keywords.
+
+2004-05-26 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
+ compound expression as lvalue errors.
+
+2004-05-24 Marius Vollmer <mvo@zagadka.de>
+
+ * dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
+ WINDER_DATA to a SCM.
+
+2004-05-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * goops.c (compute_getters_n_setters, create_standard_classes,
+ scm_add_slot): Compute closures by calling scm_i_eval_x on a
+ lambda expression rather than creating them with scm_closure.
+
+2004-05-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
+ misplaced syntactic keywords. This will not work unless guile's
+ defmacro feature is deprecated.
+
+ (scm_m_case): Fixed a bug that caused the list of labels to grow
+ with every case form.
+
+2004-05-19 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_round_number): For inum and big, just return x. For
+ real, use scm_round for 2^54-1 etc problems covered there.
+
+ * numbers.c (trunc): Remove #define to scm_truncate when the C library
+ doesn't provide trunc. This was for when `truncate' was done as a
+ scm_tc7_dsubr, no longer required.
+
+ * threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
+ to stack marking call, two parameters and no cast on t->base.
+
+2004-05-18 Marius Vollmer <mvo@zagadka.de>
+
+ * hashtab.c (rehash_after_gc): Bug fix: properly link the
+ processed hashtables back into the weak_hashtables list. Thanks
+ to Bill Schottstaedt!
+
+2004-05-16 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (unmemoize_quote): New static function.
+
+ (scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
+ representation of 'quote' and '@slot-ref' to an improper list.
+ This reduces execution time, the number of cells used to hold the
+ memoized code, and thus also reduces garbage collection time.
+
+ (scm_unmemocopy): Use unmemoize_quote for quote expressions.
+
+ (SCM_CEVAL): Changed macro handling to also work with macros that
+ return improper lists. Added an assertion, that the code returned
+ by a macro transformer will not lead to cycles in the memoized
+ code.
+
+2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ No functional change, just rearrangements of functions within the
+ file.
+
+ * eval.c (scm_ilookup, scm_unbound_variable_key,
+ error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
+ the definitions used for execution, since that's where they will
+ belong to later.
+
+2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * numbers.h (SCM_SLOPPY_FRACTIONP): Removed. It was not used
+ throughout guile, has not been part of an official release yet,
+ and the concept of sloppy predicates has never been a good idea.
+
+ (SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
+ SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
+ Simplified.
+
+2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
+ to make explicit what happens.
+
+2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
+ explicit what happens.
+
+ * guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
+ SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
+
+2004-05-11 Marius Vollmer <mvo@zagadka.de>
+
+ * scmsigs.c (scm_sigaction_for_thread): Validate that the handler
+ is indeed a procedure when it isn't a number.
+
+2004-05-10 Marius Vollmer <mvo@zagadka.de>
+
+ Convert floating point numbers into strings with an arbitrary
+ radix. Thanks to Richard Todd!
+
+ * numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
+ fit.
+ (fx): Removed.
+ (scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
+ number_chars): New, to support variable radices.
+ (idbl2str): Use above instead of the old base-10 only tables.
+ (iflo2str): Pass on new RADIX argument to idbl2str.
+ (scm_number_to_string): Pass radix to iflo2str.
+ (scm_print_real, scm_print_complex): Explicitly pass radix 10 to
+ iflo2str.
+ (scm_init_numbers): Call init_dblprec and init_fx_radix for all
+ possible radices.
+
+2004-05-10 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_logbit_p): Correction to test above the end of an
+ inum. Reported by Jan Konecny.
+
+2004-05-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
+
+ * gc.h (scm_t_cell): Fields are now of type SCM instead of
+ scm_t_bits. Updated all users.
+ (SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
+ duplicating the code.
+ (SCM_CELL_OBJECT_LOC): New.
+ (SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
+ (SCM_CELL_WORD_LOC): Moved to "deprecated.h".
+
+ * smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
+ SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,
+ SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3,
+ SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3,
+ SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
+ SCM_SMOB_OBJECT_3_LOC): New.
+ * smob.c (scm_i_set_smob_flags): New function.
+
+ * dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
+ hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
+ random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
+ Use SCM_SMOB_* instead of SCM_CELL_* as appropriate. Use
+ SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
+ zeroth word directly. Use SCM_SMOB_PREDICATE as appropriate.
+
+ * numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
+ taking the address of SCM_CELL_WORD_1, the latter being no longer
+ an lvalue.
+
+ * variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
+ of casting SCM_CELL_WORD_LOC.
+
+2004-05-02 Kevin Ryde <user42@zip.com.au>
+
+ * eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
+ --disable-deprecated. Reported by Andreas Vögele.
+
+ * filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in
+ particular on HP-UX). Reported by Andreas Vögele.
+
+ * list.c (varargs.h): Remove, leave just stdarg.h which is all the
+ code has support for. Fixes building with AIX cc, which is ansi but
+ doesn't define __STDC__. Reported by Keith Crane.
+ (var_start): Remove macro, this variation no longer required.
+ (scm_list_n): Use va_start directly.
+
+2004-05-01 Kevin Ryde <user42@zip.com.au>
+
+ * continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which
+ is now gone. Reported by Andreas Vögele.
+
+2004-04-28 Kevin Ryde <user42@zip.com.au>
+
+ * backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT,
+ mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
+ ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
+ subscript. Reported by Andreas Vögele.
+ Also cast through unsigned char to avoid passing negatives to those
+ macros if input contains 8-bit values.
+
+ * num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case,
+ corrections to range check for signed numbers. Remove
+ scm_remember_upto_here_1(num) from these checks, since num is used
+ subsequently anyway.
+
+ * num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to
+ avoid warning from gcc 3.4. Reported by Hyperdivision.
+
+ * numbers.c (scm_bit_extract): Use min instead of MIN.
+ (MIN): Remove, this conflicts with similar macro defined by limits.h
+ on HP-UX. Reported by Andreas Vögele.
+
+ * stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in
+ particular on HP-UX). Reported by Andreas Vögele.
+
+ * threads.c (scm_threads_mark_stacks): Correction sizet -> size_t.
+ Reported by Andreas Vögele.
+
+ * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long),
+ for the benefit of hpux11 where pthread_mutex_t is 88 bytes. Reported
+ by Andreas Vögele.
+
+2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (s_macro_keyword): New static identifier.
+
+ (scm_m_define): Change order to first create binding and
+ evaluating the expression afterwards.
+
+ (scm_m_set_x): Memoize complete set! expression. Only leave
+ symbols if no binding exists at memoization time. Throw error if
+ assigning to a syntactic keyword.
+
+ (lazy_memoize_variable): New function.
+
+ (CEVAL): When execution set!, perform lazy memoization if
+ unmemoized symbol is detected.
+
+ * modules.c (module_variable): Return variables with unbound
+ value.
+
+ * tags.h: Fix comment.
+
+2004-04-25 Kevin Ryde <user42@zip.com.au>
+
+ * chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase,
+ scm_c_downcase): Use ctype.h toupper and tolower. This will be useful
+ in 8-bit locales, and ensures consistency with char-upper-case? and
+ char-lower-case? which already use ctype.h.
+ (scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers):
+ Remove.
+ * chars.c, chars.h, init.c (scm_tables_prehistory): Remove.
+
+ * socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p
+ call. Reported by Hyperdivision.
+
+ * threads.c (scm_yield): Correction, actually call scm_thread_yield.
+ Reported by Hyperdivision.
+
+ * unif.c (s_scm_make_uve): Remove unused local variable. Reported by
+ Hyperdivision.
+
+2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ Hide the implementation of ilocs and isyms in eval.c.
+
+ * deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
+ SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
+ SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
+ SCM_ICDRP): Deprecated and added to deprecated.h. Moved from
+ eval.h to eval.c.
+
+ * deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
+ SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
+ scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
+ (SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
+ scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
+ deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and
+ renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and
+ renamed to ISYMNUM.
+
+ * eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
+ (scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
+ Extracted printing of ilocs and isyms to guile internal functions
+ scm_i_print_iloc, scm_i_print_isym of eval.c.
+
+2004-04-22 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift.
+
+ * numbers.c (scm_round): Test for x already an integer, to avoid bad
+ rounding in x+0.5 when x is a big value already an integer. In
+ certain hardware rounding cases x+0.5 can give an adjacent integer,
+ leading to that as the result, when we really just wanted x itself.
+
+2004-04-19 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (scm_unmemocopy): Fixed unmemoization of let*.
+
+ (deval_args, CEVAL): Minor improvements: Reduced variable scopes,
+ added const qualifiers, cast intentionally unused expressions to
+ void for emphasis, improved comment.
+
+2004-04-18 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag,
+ scm_tc8_isym): Renamed scm_tags to scm_tc8_tags. Renamed
+ scm_tc9_flag to scm_tc8_flag. Introduced new identifier
+ scm_tc8_isym. Defined tc8-tags relative to scm_tc3_imm24.
+ Defined the tc8-tag for flags to be 0x04, which will mean that
+ SCM_BOOL_F will also have the value 0x04 instead of 0x013c. Due
+ to the reduced number of bits and the simpler bit pattern for
+ SCM_BOOL_F, certain machines may be able to use more efficient
+ processor instructions to deal with SCM_BOOL_F.
+
+ (SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed. These have
+ never been defined in a released version, thus no need to
+ deprecate them.
+
+ (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
+ instead of tc9 tags.
+
+ (SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
+ of tc9 tags.
+
+ (SCM_MAKSPCSYM): Removed. It is almost impossible that user code
+ could have used this definition.
+
+ (SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
+ SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
+ SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
+ as isyms, as special isyms don't exist any more.
+
+2004-04-18 Kevin Ryde <user42@zip.com.au>
+
+ * filesys.c (scm_readdir): Use readdir_r when available, for thread
+ safety.
+
+ * numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than
+ explicit swapping code.
+
+2004-04-15 Kevin Ryde <user42@zip.com.au>
+
+ * cpp_sig_symbols.in: Add SIGSYS.
+
+ * list.c (scm_append_x): Use iterative style, to avoid non-tail
+ recursion.
+
+ * numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac,
+ frac/big and frac/frac, use scm_less_p for exact comparison.
+
+ * numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code
+ with big/inum.
+
+ * numbers.c (xisinf): Add a comment about solaris 7 lacking isinf.
+
+2004-04-06 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.
+
+ * chars.h (scm_init_chars): change scm_{upcase,downcase} to
+ scm_c_{up,down}case.
+ (SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
+ when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
+
+2004-04-06 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_ash): Remove stray "}" in docstring.
+
+ * numbers.c (scm_make_ratio): For inum/bignum integer detection, use
+ x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
+ calling mpz_cmp_ui in most cases.
+
+ * numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
+ for big == abs(most-negative-fixnum) special case.
+ (abs_most_negative_fixnum): Remove, no longer used.
+
+ * scmsigs.c (scm_sigaction_for_thread): Correction to signum range
+ test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
+ calling (sigaction NSIG).
+
+ * simpos.c (scm_system_star): Fix execargv memory leak, merge parent
+ and fork error cases to do this.
+
+2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (CEVAL): Don't distinguish between short and long
+ instructions when dispatching - just always dispatch on the
+ instruction code, which is common for short and long instructions.
+ Further, removed unnecessary goto statements and added comment.
+
+2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (scm_unmemocopy): Don't distinguish between short and
+ long instructions when dispatching - just always dispatch on the
+ instruction code, which is common for short and long instructions.
+ Further, removed unnecessary goto statements, fixed indentation
+ and replaced SCM_IMP predicates by SCM_NULLP.
+
+2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
+ comparison with SCM_ILOC00. In CEVAL, eliminate goto-label
+ 'checkmacro'.
+
+2004-03-31 Kevin Ryde <user42@zip.com.au>
+
+ * simpos.c: Include <signal.h> for SIG_IGN and friends.
+
+2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
+ SCM_DEBUGGINGP:
+
+ * debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
+ eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
+ SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
+ single interface that also matches the naming conventions.
+ Probably scm_debug_mode_p should be part of the private interface
+ anyway.
+
+ * debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
+ eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
+ scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
+ to scm_debug_mode_p.
+
+
+ Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
+
+ * eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
+ (scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
+ from debug.h to eval.h.
+
+ * debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
+ more, just leave it with setting scm_debug_mode_p, which is
+ equivalent for practical purposes.
+
+ * deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
+ instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
+
+ * gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
+
+ * eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
+ static and renamed it to ceval throughout. Provide a new exported
+ but deprecated function scm_ceval as a wrapper for backwards
+ compatibility. The same is done for the deval/scm_deval pair of
+ functions.
+
+ * eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
+ throughout. Defined CEVAL to ceval or deval, based on compilation
+ phase.
+
+ * eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
+ to ceval and deval instead of calling *scm_ceval_ptr.
+
+ * eval.c (dispatching_eval): New deprecated static function.
+
+ * eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
+ to emulate its old behaviour as closely as possible.
+
+
+ Change the evaluator such that only expressions for which pair? is
+ true are passed to CEVAL, and such that all other expressions are
+ evaluated outside of CEVAL:
+
+ * eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
+ expression that is assumed to be memoized already. All but
+ expressions of the form '(<form> <form> ...)' are evaluated inline
+ without calling an evaluator.
+
+ * eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
+ expressions of the form '(<form> <form> ...)' inline without
+ calling an evaluator.
+
+ * eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
+ the special case of unmemoized symbols passed on the top level.
+
+ * eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
+ is known that the expression passed to CEVAL is of the form
+ '(<form> <form> ...)'. Remove handling of the tc7-objects, since
+ now it is known that the input expression of CEVAL is a pair.
+
+2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (is_self_quoting_p): New static function.
+
+ (scm_m_quote): Use is_self_quoting_p.
+
+ (copy_tree): Corrected typo in comment.
+
+2004-03-28 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * eval.c (s_scm_copy_tree): idem.
+
+ * list.c (s_scm_filter): remove "pointer" from doc string.
+
+ * gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
+
+ * goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
+
+ * backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
+ (display_frame): idem.

+
+ * numbers.c (scm_modulo): For inum/big and big/big, remove test of
+ big==0 since that never occurs.
+
+ * numbers.c, numbers.h (scm_modulo_expt): Renamed from
+ scm_modular_expt, matching scheme level name `modulo-expt'.
+
+ * numbers.c (scm_modular_expt): Return a negative remainder for a

+
+ * eval.c: Separated some definitions relevant for execution from
+ the memoization part of the file.
+
+ (copy_tree): New static function
+
+ (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
+ structures are detected now and will lead to an exception instead
+ of forcing guile to run in an endless loop, using up all the
+ system's memory. Second, arrays in the cdr of an improper list
+ are now copied. See the new test cases in eval.test.
+
+2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * posix.c (scm_gethostname): Make sure len is initialised before

+
+ * read.c (skip_scsh_block_comment): Also recognize '\r' as a line

+
+ * eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
+ themselves. Thanks to Han-Wen Nienhuys!
+
+ * list.c: Changed docstrings so that they no longer talk about

+
+2004-03-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * gc.c: remove set_debug_cell_accesses! when
+ SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should

+
+2004-03-21 Kevin Ryde <user42@zip.com.au>
+

+2004-03-03 Mikael Djurfeldt <mdj@chunk.mit.edu>
+
+ * threads.c, threads.h (scm_c_scm2thread): New function.
+
+2004-02-29 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
+ available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
+ particular don't assume "defined (__alpha__) && ! defined (linux)"
+ means OSF. Remove "SCO" code, which was not really SCO specific and
+ which John W. Eaton advises should be long past being needed.
+
+ * posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
+ error throw.
+
+2004-02-24 Kevin Ryde <user42@zip.com.au>

+
+2004-02-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * list.c (scm_list_n): validate non-immediate arguments;

+
+ * gc.h (scm_gc_cells_collected): Removed duplicated declaration.
+ Thanks to Bill Schottstaedt!

+
+2004-02-18 Kevin Ryde <user42@zip.com.au>
+
+ * num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
+ order parameter to mpz_import, in fact with just one word there's no
+ order to worry about at all.
+
+ * numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
+ and frac==complex, make an exact comparison rather than converting
+ with fraction2double.
+
+ * posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
+ shared library, since environ is not directly available there.
+
+ * script.c (scm_shell_usage): Print to stdout for --help, per GNU
+ standard.
+
+ * stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
+ errno EINVAL in case localtime and gmtime don't set it.
+ (scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
+ SCM_SYSERROR, since mktime and strptime generally don't set errno.
+
+2004-02-16 Kevin Ryde <kevin@swox.se>
+
+ * gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes,
+ which were permitted in the past for these.

+ previous change to numbers.c.
+
+ * script.c (scm_shell_usage): Print bug-guile email address, as per

+ port, and remove shared port-line @defun.
+ (scm_set_port_column_x): In docstring, there's no default to current
+ input port, note first column is 0, remove shared set-port-line!
+ @defun.
+
+ * ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
+ convert args the same way that array-set! does.
+
+ * unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
+ for dvect.
+ (scm_array_p): Add missing "break"s in switch, fix llvect test look
+ for "l" not "s", fix dvect to be false for singp(prot) since such a
+ value is for fvect.
+ (scm_array_prototype): Return 1/3 for dvect, rather than 0.33..33.
+ (exactly_one_third): New variable.
+ (scm_init_unif): Initialize it.

+ (scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen. Make
+ handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and

+ `escaped-parens' option set.
+ (scm_read_token): If elisp vector syntax active, disallow [ and ]
+ in tokens.
+ (scm_lreadparen): Rewrite as interface to scm_lreadparen1.

+
+2004-01-23 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * eval.c (m_expand_body): remove stray variable new_body.
+
+2004-01-22 Marius Vollmer <mvo@zagadka.de>
+
+ * eval.c (m_expand_body): Rewrite the expression in place (by

+ when no definitions are found. Do not return rewritten expression
+ to emphasize the in-place rewriting. Changed all users.
+
+2004-01-19 Han-Wen Nienhuys <hanwen@xs4all.nl>
