+
+ * 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.
(copy_tree): Corrected typo in comment.
->>>>>>> 1.2042

* eval.c (s_scm_copy_tree): idem.
