+
+ * 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.

+
+ * 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".

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

+ * dynl.c (scm_dynamic_link): Moved allocating of the memory for
+ the dynamic object data below the linking of the object to avoid
+ memory leak when the linking code throws an error. Now the code
+ leaks a whole dynamically linked library when must_malloc throws,
+ but that should be much less likely.
+
+Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>

+
+Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
+
+ * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since

+
+ * root.c: Establish a reliable catch-all handler for the new root.
+ After all the Scheme handler function might signal an error too,
+ and we don't want to lose that.

+ (cwdr_outer_body): New function, to establish the user's handler,
+ and pass control to cwdr_inner_body.
+ (cwdr): Establish the reliable catch-all handler here, and pass

+ * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
+ * extchrs.c (xmbtowc): Make the second arg a normal char, not
+ unsigned, because that's what the ANSI function takes.
+ * extchrs.h (xmbtowc): Corresponding change to prototype.
+ * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
+ uchars here.
+ * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA

+ * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
+ char.

+ top of the word, it should be unsigned.
+
+ * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
+ is defined, to avoid warnings; it's only used in the
+ conflict-checking code. Which might go away anyway.
+ (SCM_CEVAL): All goto's targeting the `dispatch' label are in
+ conditionals; put the label definition in an #if too, to stifle
+ warnings.
+
+ * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and

+ * Makefile.in: Regenerated.
+
+Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
+
+ * guile-snarf.in: Changed regexp to support CPPs that insert

+
+ * load.c (scm_init_load_path): Append $(datadir)/guile to

+
+ * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic

+Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
+
+ * regex-posix.c (scm_regexp_exec): Use the `start' argument if
+ supplied. (Change from Tim Pierce.)
+
+Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
+ 23:47:01 1997" changelog: Slots are now initialized with `#f' by
+ default and not `()'. `#f' is the canonical non-value in Scheme,
+ right?
+
+Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * struct.c (struct_printer): New variable that holds a handle on
+ the Scheme variable *struct-printer*. This variable can be set by
+ Scheme code to override the printing of structures.
+ (scm_print_struct): If struct_printer is set, call it. If it is
+ not set, or returns #f, print the structure in the old fashion.
+ Include "eval.h" for scm_apply.
+
+Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * struct.c (scm_struct_ref, scm_struct_set_x): Use
+ scm_struct_i_n_words to get the number of fields, not
+ -scm_struct_n_extra_words.
+
+ On the route to fancier struct printing:
+ * struct.c (scm_print_struct): New function to print a structure.
+ Include "genio.h" to support it. This function doesn't do
+ anything interesting right now, but I think it should be here
+ anyway.
+ * struct.h: Include "print.h" and add prototype for
+ scm_print_struct.
+ * print.c (scm_iprin1): Call scm_print_struct instead of trying to
+ print structures ourself.
+
+Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
+
+ * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]

+
+ * scmsigs.h, async.h: updated.
+
+ * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
+ loop.
+
+ * posix.c (scm_uname): interpret only negative values as an error.
+ Solaris normally returns a positive value.
+
+ * script.c (scm_compile_shell_switches): if we are not going into
+ an interactive repl, set scm_mask_ints to zero so that asyncs can
+ run.
+
+ * simpos.c (scm_system): don't ignore/unignore signals around
+ the "system" call.
+
+ * posix.c (scm_open_pipe): don't ignore/unignore signals around
+ the "popen" call.
+
+ * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
+ done in boot-9.scm instead.
+
+ * scmsigs.c, async.c: Major rewriting of signal handling code.
+ (scm_sigaction): new procedure.
+ (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
+ timing.
+ (scm_raise): return unspecified, throw error on failure.

+
+ * regex-posix.c (scm_init_regex_posix): Register the "regex"

+ module.
+
+Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
+
+ * eval.c: Include scmconfig.h at the beginning of the file so that
+ HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
+ pointing this out.
+
+ * regex-posix.c: #include "_scm.h" before conditionally #including
+ <regex.h>; the former defines HAVE_REGCOMP.
+
+ * regex-posix.c: #include <regex.h> conditionally, so the file is
+ CPP'able (for dependency scanning) even on systems that don't have
+ a <regex.h> header.
+
+Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
+
+ Add new R4RS-compliant syntax for keywords.

+ option.
+
+Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
+

+
+ * init.c: Include regex-posix.h.

+
+ * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed

+
+ * fports.c (print_pipe_port): New function.
+ (scm_fptob): Use print_pipe_port instead of scm_prinport; the
+ latter doesn't even take the right arguments.
+
+ * Makefile.am: Increment shared lib revision number. I think
+ sometimes the uninstalled Guile finds the installed shared lib;
+ Gord says doing this might help. As things turned out, I can't
+ say whether it does.
+ * Makefile.in: Regenerated.
+
+ * gh_init.c (gh_enter): Cast c_main_prog to a void * before
+ passing it as the closure argument to scm_boot_guile. (Bill

+
+ * script.c (scm_find_executable): Use prototype-style definition

+ and then use a K&R declaration. I wonder if stuff like this will
+ go away if we compile with -Wrequire-prototypes, or whatever that
+ is... (Bernard URBAN)

+
+ * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):

+
+Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
+
+ * posix.c: don't include <sys/select.h> or define macros for

+
+ * filesys.c (scm_select): make the fifth parameter microseconds,

+
+ From Tim Pierce:
+ * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):

+ (scm_async_click): don't send SCM_TICK_SIGNAL.
+ (scm_init_async): don't initialize %tick-thunk.
+
+ * the following change doesn't affect the Scheme interface:
