* memory.texi: Comment out the relocating allocator description.
* manual/signal.texi: Remove reference to relocating allocator.
* manual/top-menu.texi: Regenerated.
* posix/fnmatch.c: Implement [: :] and change to recognize
^ as negation only when not _POSIXLY_CORRECT.
* sysdeps/generic/glob.c: Add several optimizations.
* posix/glob.h: Undefine __PMT to prevent warnings.
Reported by Roland McGrath.
* posix/regex.c: Define namespace macros only for _LIBC.
* sysdeps/arm/dl-machine.h: Fix typo.
* sysdeps/unix/sysv/sysv4/solaris2/sigpending.c: New file.
* sysdeps/unix/sysv/sysv4/solaris2/sigstack.c: New file.
* sysdeps/unix/sysv/sysv4/solaris2/sigwaitinfo.c: New file.
* sysdeps/unix/sysv/sysv4/solaris2/syscalls.list: Add sigaltstack,
sigpending, sigqueue, and sigtimedwait.
* sysdeps/unix/sysv/sysv4/solaris2/sparc/sparc32/syscall.S: New file.
* timezone/leapseconds: Update from tzdata1998f.

* stdio/Versions [GLIBC_2.1]: Add fputs_unlocked.
* libio/stdio.h: Fix typo.
1998-07-19 Roland McGrath <roland@baalperazim.frob.com>
* sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_start): #if 0 out the
magic memobj port arg parsing stuff. Fix it someday when we are ready
to really use it.
(_dl_sysdep_output): New function, modified from _dl_sysdep_error.
(_dl_sysdep_error, _dl_sysdep_message, _dl_sysdep_fatal): Removed.
1998-07-19 Roland McGrath <roland@baalperazim.frob.com>

1998-07-19 Roland McGrath <roland@baalperazim.frob.com>
* sysdeps/posix/sigsuspend.c: Define __sigsuspend with sigsuspend as
a weak alias.

* Makerules (map-file): Don't use $(wildcard) to find the
generated version script, instead look in $(version-maps).
($(common-objpfx)libc.so): Only depend on libc.map if versioning
is used.
* extra-lib.mk ($(objpfx)$(lib).so): Only depend on version script
if versioning is used. Don't use $(wildcard) to find the
generated version script, instead look in $(verson-maps).

* sysdeps/generic/segfault.c: Rename GET_EIP to GET_PC. Remove
unused function handle.

* sysdeps/unix/sysv/linux/i386/sigcontextinfo.h: Likewise.
* debug/catchsegv.sh: Fix argument processing, quoting and various
typos. Put the crash info always in the current directory. Find
program in $PATH if it contains no directory component.
* Makerules (install-lib.so-versioned,
install-lib.so-unversioned): New variables.
(install-lib-nosubdir): Depend on unversioned libs in
slibdir, not libdir.
