* _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.
* boot-9.scm: signal-handler, alarm-thunk: removed.
don't define ticks-interrupt etc.
top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
during call to scm-style-repl.
* acconfig.h: mention HAVE_RESTARTS.
* configure.in: check for sigaction and restartable system calls.
struct stat doesn't have the st_blocks field. We take care of
that case in the code. Replace AC_STRUCT_ST_BLOCKS with its
definition, edited appropriately.
* configure: Regenerated.
* configure.in: Don't link against -lnsl or -lsocket unless we
actually need to. This causes trouble on Irix. (Thanks to Larry
Schwimmer.)
* Makefile.am (SUBDIRS): List libguile last, so qt gets built
first.
* Makefile.in: Regenerated.
* aclocal.m4, configure: Regenerate, with modern definition of
CY_AC_WITH_THREADS. Where did the old text come from? Creepy...
no plugins.
* configure.in: Merged the old text from qt/configure.in and
libguile/configure.in; Tom Tromey says automake only wants one
configure.in script. This seems fishy, but...
* Makefile.am: List the subdirectories explicitly; no more PLUGIN
gubbish.
* acconfig.h, acinclude.m4: Moved here from libguile, since
libguile's configure script lives here now.
* AUTHORS, INSTALL, README: Updated.
* Makefile.in, aclocal.m4 configure: Regenerated. Just like
amputated amphibian limbs.
snapshots. Other changes in subdirectories.
* Makefile.in (dist): Rewritten --- the old target was out of
date, dependent on files that we don't have, and relied on GNU
tar. The new target is simpler.
(VERSION, srcdir, dist_dirs): New variables.
(DISTFILES): Renamed from localfiles. Added GUILE-VERSION and
TODO.
(localtreats): Variable removed. We don't have this file.
(info): cd to doc and make info there; don't make info in every
${subdir}; those Makefiles don't know what to do.
(distname, distdir, treats, announcefile): Variables removed.
(manifest-file): Target removed.
(dist-dir): New target, responsible for distributable files in
this directory.
(GZIP, GZIP_EXT, TAR_VERBOSE, DIST_NAME): New variables,
controlling the 'dist' target.
* configure.in: Substitute GUILE-VERSION into the top-level
Makefile. Build doc/Makefile from doc/Makefile.in.
