* scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
HAVE_RESTARTABLE_SYSCALLS.
(scm_init_scmsigs): use siginterrupt if it's available. not
everyone who has restartable syscalls has SA_RESTART it seems.
(scm_sigaction): use scm_num2long/scm_long2num when converting
SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
scm_integer_p to test the type.
* configure.in: use AC_SYS_RESTARTABLE_SYSCALLS instead of
testing for SA_RESTART.

* _scm.h, scmsigs.c: replace HAVE_RESTARTS with
HAVE_RESTARTABLE_SYSCALLS.
support.
* guile-readline: New directory, see ChangeLog there.
* configure.in: Cause configure to descend into guile-readline
dir.
* Makefile.am: Likewise for make.
* NEWS: Explain how to activate the readline support.
* configure, Makefile.in, aclocal.m4: Regenerated.
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.
starting with guile_cv_; ac_cv_ is autoconf's namespace.
The type of the argument to usleep varies from system to system,
as does the return type. We really shouldn't be redefining usleep
at all, but I don't have time to clean that up before the 1.3
release. It's on the schedule for afterwards.
* configure.in: Cache results from usleep return value test.
Test for the type of the usleep argument, and cache that too.
* acconfig.h (USLEEP_ARG_TYPE): New macro.
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.
