+ (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
+ Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
+ and _longjmp with the new symbols. Emacs already uses _setjmp if

+ sigsetjmp but not _setjmp, such as some versions of Solaris and

+
+ Simplify SIGIO usage (Bug#12408).

+ * sysdep.c (croak): Remove; no longer needed. This bit of

+ Avoid _setjmp/_longjmp problems with local nonvolatile variables.
+ If a nonvolatile local variable is written before a _longjmp to

+ (Ffrexp): Do not special-case zero, as frexp does the right thing
+ for that case.
+ (Flogb): Do not use logb, as it doesn't have the desired meaning
+ on hosts that use non-base-2 floating point. Instead, stick with

+ This simplifies the code, and makes it a bit smaller and faster,
+ and (most important) makes it easier to clean up signal handling
+ since we can stop worring about floating-point exceptions in
+ library code. That was a problem before C89, but the problem
+ went away many years ago on all practical Emacs targets.
+ * data.c, image.c, lread.c, print.c:
+ Don't include <math.h>; no longer needed.
+ * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
+ might be autoconfigured, as that never happens.
+ * data.c (fmod):
+ * doprnt.c (DBL_MAX_10_EXP):
+ * print.c (DBL_DIG):
+ Remove. C89 or later always defines these.
+ * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
+ (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
+ (arith_error, domain_error, domain_error2):
+ Remove all this pre-C89 cruft. Do not include <errno.h> as that's
+ no longer needed -- we simply return what C returns. All uses removed.
+ (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
+ the wrapped code.
+ (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
+ Remove. All uses expanded, as these macros are no longer used
+ more than once and are now more trouble than they're worth.
+ (Ftan): Use tan, not sin / cos.
+ (Flogb): Assume C89 frexp.
+ (fmod_float): Assume C89 fmod.
+ (matherr) [HAVE_MATHERR]: Remove; no longer needed.
+ (init_floatfns): Remove. All uses removed.

+ More signal-handler cleanup (Bug#12327).
+ * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
+ Problem introduced when merging patches. Noted by Eli Zaretskii in
+ <http://bugs.gnu.org/12327#67>.
+ * floatfns.c: Comment fix.
+ * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
+ SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
+ and anyway the declaration is harmless even if SIGDANGER is not defined.
+ * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
+ defined BROKEN_FIONREAD). systty.h formerly did this, but other
+ source files not surprisingly expected syssignal.h to define, or
+ not define, SIGIO, and it's cleaner to do it that way, for consistency.
+ Include <sys/ioctl.h>, for FIONREAD.
+ * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
+ This eliminates a problem whereby other files mysteriously had
+ to include "syssignal.h" before including "systty.h" if they
+ wanted to use "#ifdef SIGIO".

+
+ Signal-handler cleanup (Bug#12327).
+ Emacs's signal handlers were written in the old 4.2BSD style with
+ sigblock and sigmask and so forth, and this led to some
+ inefficiencies and confusion. Rewrite these to use
+ pthread_sigmask etc. without copying signal sets around. Also,
+ get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
+ 'signal', and instead use functions that do not attempt to take
+ over the system name space. This patch causes Emacs's text
+ segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
+ * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
+ Do not include <signal.h> or "syssignal.h", as these
+ modules do not use signals.
+ * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
+ * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
+ Do not include <signal.h>, as "syssignal.h" does that for us now.
+ * atimer.c (sigmask_atimers): New function.
+ (block_atimers, unblock_atimers): New functions,
+ replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
+ All uses replaced.
+ * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
+ no longer needed here.
+ * emacs.c (main): Inspect existing signal handler with sigaction,
+ so that there's no need to block and unblock SIGHUP.
+ * sysdep.c (struct save_signal): New member 'action', replacing
+ old member 'handler'.
+ (save_signal_handlers, restore_signal_handlers):
+ Use sigaction instead of 'signal' to save and restore.
+ (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
+ New function. All users of 'signal' modified to use set_sighandler
+ if they're writeonly, and to use sys_signal if they're read+write.
+ (emacs_sigaction_init, forwarded_signal): New functions.
+ (sys_signal): Remove. All uses replaced by calls to sigaction
+ and emacs_sigaction_init, or by direct calls to 'signal'.
+ (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
+ (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
+ all uses replaced by pthread_sigmask etc. calls.
+ * syssignal.h: Include <signal.h>.
+ (emacs_sigaction_init, forwarded_signal): New decls.
+ (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
+ (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
+ (sigmask, sys_sigmask): Remove; no longer needed.
+ (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
+ (sigblock, sigunblock, sigfree):
+ (sigsetmask) [!defined sigsetmask]:
+ Remove. All uses replaced by pthread_sigmask.
+ (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
+ no longer need to be replaced, and its typical old uses
+ are now done via emacs_sigaction_init and sigaction.
+ (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
+ (sys_sigdel): Remove; unused.
+ (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
