ac_cv_lib_readline_readline; the latter isn't set any more, since
we look for 'main' in libreadline now. Add quotes around
reference to the variable references, too, so this will work even
when a variable's value is the empty string.
* configure: Regenerated.
long, not only when a float is the same size as a long. This gets
us SCM_SINGLES defined on alphas. (Thanks to Clark McGrew.)
* configure: Regenerated.
* configure.in: Remove tests for usleep's argument type; we only
need that if we're going to replace it.
* acconfig.h (USLEEP_ARG_TYPE): Delete. All the other SLEEP
garbage is needed just to use usleep and sleep without compiler
warnings.
* configure: Regenerated.
whether `bzero' and `usleep' have declarations --- that's going
back to the bad old days before autoconf. Remove the call to
AC_CANONICAL_HOST and the subsequent case statement.
(GUILE_FUNC_DECLARED): New m4 macro. Use it to check for
declarations for `bzero', `usleep', and (new!) `strptime'.
* acconfig.h: (DECLARE_BZERO, DECLARE_USLEEP): Removed.
(MISSING_BZERO_DECL, MISSING_USLEEP_DECL, MISSING_STRPTIME_DECL):
Added. I think this naming convention is more consistent with the
rest of autoconf; names generally describes the system, not what
the package should do to accomodate the system.
* configure: Regenerated.
* configure: Regenerated.
* HACKING: Ask people not to make changes that introduce those
warnings. Now I have to go through the code and actually bring it
up to standards... :(
* qthreads.m4: New file, which knows how to configure the qthreads
library.
* configure.in: Replace all thread package selection code. Do the
--with-threads argument processing here. Enable the appropriate
thread interface files in libguile. Remove all qthreads
configuration code; call QTHREADS_CONFIGURE instead. Set
GUILE_LIBS using the info provided by QTHREADS_CONFIGURE.
* threads.m4: Removed; not used any more.
* Makefile.am (aclocal_DATA): Mention qthreads.m4, not threads.m4.
* Makefile.in, aclocal.m4, configure: Rgnrtd. (Sv th vwls!)
Note that these were regenerated with the tools available from
Cygnus's source tree, which have patches not available to the
general public. I'm not sure this was a good idea; feel free to
revert them to the latest released versions of the tools.
(scm_usleep): Return SCM_INUM0 on those systems.
* coop.c (usleep): Return void on some systems.
* configure.in: Define USLEEP_RETURNS_VOID on some systems.
cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
(libpath.h, versiondat.h): Replaced dependency on Makefile with
dependencies on $(srcdir)/Makefile.in
$(top_builddir)/config.status in order to avoid circularity.
* configure.in (GUILE_LIBS): New variable. Contains libraries
which libguile needs to be linked with. Substituted into
libpath.h.
* threads.m4 (threads_package): Don't add $LDFLAGS and $LIBS to
$cy_cv_threads_libs.
* ltconfig, ltmain.sh, config.sub, config.guess: Updated.
New automake: 1.3
* Makefile.in, aclocal.m4, configure: Regenerated.
* README: Mention new version numbers on libtool and automake.
* configure.in: AC_CHECK_FUNCS: add "system".
* 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.
