if the library is found. Otherwise, later configure-time tests,
such as the test for pthread_sigmask, generate the wrong results
on some platforms. Problem reported for FreeBSD by Nali Toja.
* configure.in (AC_STRUCT_TM, AC_STRUCT_TIMEZONE, HAVE_TM_GMTOFF):
Remove; no longer needed, now that we defer to strftime for time
zone names.
* src/editfns.c: Rewrite current-time-zone so that it invokes
the equivalent of (format-time-string "%Z") to get the time zone name.
This fixes a bug when the time zone name contains characters that
need converting from the system time locale to Emacs internal format.
This fixes a shortcoming that I introduced in my 1999-10-19 patch:
that patch fixed format-time-string to do the conversion, but
I forgot to fix current-time-zone.
(format_time_string): New function, containing most of
what Fformat_time_string used to contain.
(Fformat_time_string): Rewrite in terms of format_time_string.
This doesn't change this function's behavior.
(current-time-zone): Rewrite to use format_time_string.
This fixes the bug reported by Michael Schierl in
<http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
Jason Rumney's 2007-06-07 change worked around this bug, but
didn't fix it.
* src/systime.h (tzname, timezone): Remove no-longer-used declarations.
The check breaks 'configure' in some CentOS 5.7 x86 configurations.
The check was helpful but not essential in Solaris 2.6 (1997),
and is no longer needed in Solaris 8 (2000). Solaris 2.6 is
obsolete -- Sun dropped support for it in 2006 -- and without
access to that Silurian platform we can't maintain the code anyway.
* lib/signal.in.h, lib/sigprocmask.c, m4/gl-comp.m4:
* m4/gnulib-common.m4: Merge from gnulib.
Without this, 'configure' would say "func_gl_gnulib_m4code_pathmax:
command not found" on powerpc-apple-darwin9.8.0.
* configure.in (GC_LISP_OBJECT_ALIGNMENT): Remove.
This is now done by src/alloc.c.
* src/alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
this makes Emacs dump core during garbage collection on rare
occasions. sizeof is obviously inferior to offsetof here, so
stick with offsetof.
(GC_POINTER_ALIGNMENT): New macro.
(mark_memory): Omit 3rd (offset) arg; caller changed.
Don't assume EMACS_INT alignment is the same as pointer alignment.
msdos/mainmake.v2 (boot): Condition the value on the existence of
autogen/README, not admin/admin.el, since the latter is now part
of the release tarball.
(install): Don't copy lib-src/fns.el, as that file is no longer
generated in that directory.
msdos/sed1v2.inp (LIB_PTHREAD, LIB_PTHREAD_SIGMASK): Edit to empty.
(SETTINGS_CFLAGS, SETTINGS_LIBS): Edit these instead of
GCONF_CFLAGS and GCONF_LIBS.
msdos/sedlibmk.inp (ALLOCA_H, AR, ARFLAGS, GNULIB_CHDIR, GNULIB_DUP)
(GNULIB_FDATASYNC, GNULIB_FDOPEN, GNULIB_FSTAT, GNULIB_PCLOSE)
(GNULIB_PTHREAD_SIGMASK, GNULIB_RAISE, GNULIB_SIGACTION)
(GNULIB_SIGPROCMASK, GNULIB_SIGNAL_H_SIGPIPE, HAVE_FDATASYNC)
(HAVE_PCLOSE, HAVE_POPEN, HAVE_POSIX_SIGNALBLOCKING)
(HAVE_PTHREAD_SIGMASK, HAVE_RAISE, HAVE_SIGACTION)
(HAVE_SIGHANDLER_T, HAVE_SIGINFO_T, HAVE_SIGSET_T)
(HAVE_STRUCT_SIGACTION_SA_SIGACTION)
(HAVE_TYPE_VOLATILE_SIG_ATOMIC_T, LIB_PTHREAD)
(LIB_PTHREAD_SIGMASK, NEXT_AS_FIRST_DIRECTIVE_SIGNAL_H)
(NEXT_SIGNAL_H, REPLACE_FDOPEN, REPLACE_PTHREAD_SIGMASK)
(REPLACE_RAISE): New edits.
(gl_LIBOBJS): Remove md5.o, filemode.o, and sha1.o. Add
pthread_sigmask.o.
(@GL_GENERATE_ALLOCA_H_TRUE@, @GL_GENERATE_ALLOCA_H_FALSE@): Edit
to comment out unneeded lines.
(warn-on-use.h): Edit the recipe commands to work with DJGPP
without requiring a Unixy shell.
msdos/inttypes.h (strtoimax) [DJGPP < 2.04]: New macro.
msdos/sed2v2.inp (HAVE_ALLOCA, HAVE_DECL_STRTOLL, HAVE_DECL_STRTOIMAX)
(HAVE_STRTOLL, HAVE_SIGSET_T, HAVE_SNPRINTF): New edits.
.bzrignore: Add ./GNUMakefile.unix.
config.bat: Rename GNUMakefile, so it is not run on MS-DOS.
Rename signal.in.h and alloca.in.h.
src/sysdep.c (snprintf) [EOVERFLOW]: If EOVERFLOW is not defined,
use EDOM.
This clarifies and fixes some licensing issues raised by Glenn Morris
<http://lists.gnu.org/archive/html/bug-gnulib/2011-09/msg00397.html>.
It also merges the latest version of texinfo.tex and has some
MSVC-related changes that don't affect Emacs.
* Makefile.in (GNULIB_TOOL_FLAGS): Avoid msvc-inval, msvc-nothrow,
pathmax, and raise, since these are needed only to address
MSVC-related issues that Emacs doesn't have.
* doc/misc/texinfo.tex, lib/dup2.c, lib/gnulib.mk, lib/signal.in.h:
* lib/sigprocmask.c, lib/stat.c, lib/stdio.in.h, lib/sys_stat.in.h:
* lib/unistd.in.h, m4/dup2.m4, m4/getloadavg.m4, m4/gl-comp.m4:
* m4/include_next.m4, m4/signal_h.m4, m4/signalblocking.m4:
* m4/stdint.m4, m4/stdio_h.m4, m4/sys_stat_h.m4, m4/time_h.m4:
* m4/unistd_h.m4: Merge from gnulib.
* lib/lstat.c, lib/stat.c, m4/include_next.m4, m4/nocrash.m4:
* m4/signal_h.m4, m4/time_h.m4, m4/unistd_h.m4:
Merge from gnulib. This fixes a compilation error on Tru64 UNIX
aka OSF/1 5.1 DTK cc. There is also some mingw stuff here that
doesn't affect Emacs.
Without this fix, the command to link temacs failed due to an
undefined symbol __builtin_isnan. This is because
/usr/include/iso/math_c99.h #defines isnan(x) to
__builtin_isnan(x), but the bundled gcc, which identifies itself
as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
a __builtin_isnan.
* configure.in (isnan): Remove now-unnecessary check.
* src/floatfns.c (isnan): #undef, and then #define to a clone of
what's in data.c.
(Fisnan): Always define, since it's always available now.
(syms_of_floatfns): Always define isnan at the Lisp level.
(opsys): Remove unreachable pattern hppa*-*-linux-gnu*.
Also, remove ia64*-hp-hpux1[1-9]*, as it also sets machine=hp800,
and that can't possibly work now that src/m/hp800.h no longer exists.
* configure.in: Add header check: sys/socket.h,
ifaddrs.h, net/if_dl.h. Check for getifaddrs and freeifaddrs.
Check for sa_len in struct ifreq.ifr_addr (Bug#8477).
* src/process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
(Fnetwork_interface_list): Allocate in increments of bytes instead
of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
sockaddr.
(struct ifflag_def): notrailers is smart on OSX.
(Fnetwork_interface_info): Handle case when ifr_flags is negative.
Get hardware address with getifaddrs if available.
* m4/largefile.m4: New file, so that Emacs does not mess up when
accessing files with large inode numbers in MacOS X 10.5 and later.
* m4/nocrash.m4: New file, to avoid triggering background debugger
and/or create core dumps during 'configure'.
* build-aux/move-if-change: Renamed from move-if-change.
* build-aux/snippet/arg-nonnull.h: Renamed from arg-nonnull.h.
* build-aux/snippet/c++defs.h: Renamed from c++defs.h.
* build-aux/snippet/warn-on-use.h: Renamed from warn-on-use.h.
* build-aux/snippet/_Noreturn.h: New file, for draft C1X _Noreturn.
* .bzrignore: The autogenerated files compile, config.guess,
config.sub, depcomp, install-sh, and missing are now in build-aux.
* Makefile.in (epaths-force, sync-from-gnulib):
move-if-change is now in build-aux.
(GNULIB_TOOL_FLAGS): Avoid threadlib; this is now a prerequisite
of gnulib's pthread_sigmask module, but Emacs doesn't need it.
(mkdir): install-sh is now in build-aux.
* config.bat: c++defs.h is now in build-aux/snippets.
* configure.in: Specify AC_CONFIG_AUX_DIR with build-aux (the
usual parameter).
* lib/gnulib.mk, m4/gl-comp.m4: Regenerate.
* lib/makefile.w32-in (ARG_NONNULL_H): arg-nonnull.h moved
to build-aux/snippet.
* lib/pthread_sigmask.c, lib/stdlib.in.h, m4/extensions.m4:
* m4/getopt.m4, m4/gnulib-common.m4, m4/pthread_sigmask.m4:
Merge from gnuilib. This fixes porting bugs on Cygwin, Irix, and
Solaris, enables MacOS extensions, and enables nocrash during
'configure'.
* make-dist: Adjust to new build-aux and build-aux/snippit dirs.
* admin/notes/copyright: The files compile, config.guess, config.sub,
depcomp, install-sh, missing, and move-if-change are now in the
new build-aux subdirectory. The files arg-nonnull.h, c++defs.h,
and warn-on-use.h are now in build-aux/snippets. New file
build-aux/snippets/_Noreturn.h.
* leim/Makefile.in (install): install-sh is now in build-aux.
* lib-src/Makefile.in ($(DESTDIR)${archlibdir}): install-sh moved
to build-aux.
* msdos/sedlibmk.inp (CONFIG_CLEAN_VPATH_FILES): Adjust to snippet moves
from top level to build-aux/snippet.
* src/Makefile.in (gl-stamp): move-if-change is now in build-aux.
