+
+ * filesys.c (set_element): Return file descriptor.
+ (fill_select_type): Return the highest file descriptor.
+ (scm_select): Tell select about the highest file descriptor. On
+ some systems the SELECT_SET_SIZE can be as much as 128 bytes.
+ Therefore the extra overhead for calculating the maximum fd seems
+ to be more than compensated. Is this correct? In any case,
+ scm_internal_select will be much faster with this info.
+ (scm_select, fill_select_type, set_element): Don't accept any kind
+ of object in the file descriptor list or vector.

+
+Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
+
+ * simpos.c (scm_system): always define: use sysmissing if not
+ available. Check for HAVE_SYSTEM instead of _Windows (does
+ Windows lack system or does it have an unusable one?).
+ Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
+ Let the argument be optional: if not supplied, call system(NULL).
+
+ * ports.c (scm_close_port): relax the type check from OPPORTP to
+ PORTP; closing a closed port is allowed.
+
+1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
+
+ * fports.c (scm_fgets): Return if the last char in a chunk is
+ newline. When fgets returns a string whose length is `size-1', it

+
+ Fix a memory leak in scm_read_line and a type cast bug in the ptob.
+ * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc

+1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>

+ * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
+ and to invoke scm_shell().
+ (gh_launch_pad): took out the loading of boot-9.scm from here,
+ since it is probably best to let the user control that. In fact,
+ gh_repl() now invokes scm_shell() which does that.
+
+1997-11-23 Mark Galassi <rosalia@cygnus.com>

+
+ Even more but risky streamlining:

+

+ Scheme-level name `array-map' and renamed `serial-array-map' to
+ `serial-array-map!'.
+
+ * backtrace.c: Introduced exception handlers which now enclose
+ `display-error' and `display-backtrace' so that error reporting
+ won't get into infinite loops if an error occurs during displaying
+ of the error. This can very easily happen with user supplied
+ print call-back routines.
+
+Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * ramap.c: Added alias `array-map!' for `array-map'. (Probably,

+
+Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
+
+ * init.c (scm_boot_guile_1): Added scm_init_objects ().

+
+ * Makefile.am (libguile_la_SOURCES): Added objects.c.
+ (modinclude_HEADERS): Added objects.h.
+
+ * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
+ This test is needed at many places in the code and should be
+ abstracted. (Motivated by the need of this test in libguiletk.)
+
+ * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
+ (scm_eval_string), load.c (scm_primitive_load,
+ scm_read_and_eval_x), gh_eval.c (gh_eval_str):
+ Use SCM_EOF_OBJECT_P.
+

+
+Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>

+
+Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * list.h (SCM_LISTn): New macros. Make list creation in C code
+ prettier. The idea comes from STk.
+
+ * sequences.h, sequences.c, append.h, append.c: Removed. These
+ files implemented non-R4RS operations which would encourage
+ non-portable programming style and less easy-to-read code.
+
+ * Makefile.am (sequences.h, sequences.c, append.h, append.c):
+ Removed.
+
+ * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include

+ Otherwise confusing names can turn up in backtraces.
+ (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
+ `name'; Give names to macros as well.
+
+ * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c

+Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+* * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
+ procedures;
+ (prinmacro): Removed. The code has been moved/merged into print.c
+ in order to decrease code redundancy. We want macros to print in
+ a way equivalent to procedures, and it would be silly to duplicate
+ the required code. (We don't want to maintain two places.)
+ (macrosmob): Print field is now a NULL pointer.
+
+ * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
+ scm_macro_transformer): New prototypes.
+ (scm_tc16_macro): Declared.
+
+* * print.c (scm_iprin1): Added code for printing of macros. Macros
+ are now printed in a way equivalent to procedures.
+
+Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>

+
+ * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
+ gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
+ gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
+ gh_equal_p): Use SCM_NFALSEP, instead of testing against
+ SCM_BOOL_T. Any non-false value is true.
+
+Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
+ scm_gensym): Added prototypes.
+
+ * symbols.c (scm_gensym): New function. This will speed up
+ certain types of applications (such as macro systems) which
+ generate lots of symbols.
+
+Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
+
+Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
+
+ * unif.c (scm_shap2ra): tighten the checking of the array dimension
+ specifier, since (2) or (2 . 3) would cause SEGV.
+ (scm_transpose_array): more argument checking fixes.
+
+Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
+
+ * Makefile.in: Regenerated.
+
+Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
+
+ * Makefile.in: Regenerated, so it uses "tar", not "gtar".
+
+Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * error.c, error.h (scm_error_callback): Removed (see NEWS).
+
+Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
+
+ * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or

+ ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),

+
+Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * list.c (scm_list_append_x): Allow non-pair as last argument.
+ This is consistent with the R4RS append and is probably the
+ correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
+
+Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
+
+ * stime.h: prototype for scm_times.
+ * stime.c (scm_times): new procedure.
+ * ioext.c (scm_fseek): if the first argument is a file descriptor

+ (scm_fcntl): the first argument can now be a file descriptor. The
+ third argument is now optional.
+
+ * posix.c (scm_execl, scm_execlp): make the filename argument
+ compulsory, since omitting it causes SEGV.
+ (scm_sync): return unspecified instead of #f.

+
+ * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
+ (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
+ argument to SCM_ASSERT. Furthermore, the name of the function
+ should be passed as first argument when signalling
+ SCM_WNA. (Thanks to Thomas Morgan)
+
+ * gsubr.c (scm_gsubr_apply): From Radey Shouman
+ <shouman@zianet.com>: "The switch in scm_gsubr_apply that
+ dispatches on the number of actual args has a default case
+ reporting an internal error. This is a vestige from a version
+ that mallocated a SCM vector to hold the arguments. In the
+ current version this check is too late: if it ever happens we will
+ have already overstepped the bounds of the array.
+
+ Also, the patch [...] adds a check for too many actual arguments."
+
+ mdj: Removed check for "internal programming error".
+
+Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>

+ * ioext.h: fix up prototypes.
+ * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
+ Scheme name is now dup->fdes.
+ (scm_dup_to_fdes): make the second argument optional and
+ fold in the functionality of scm_primitive_dup.
+ (scm_primitive_dup): deleted.
+
+Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
+
+ * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.

+ Scheme.
+ * print.h (scm_printer_apply): New prototype.

+
+ * ioext.h: removed scm_duplicate_port prototype.
+
+ * ioext.c (scm_primitive_dup2): return the new file descriptor
