* dirent/scandir.c: Undo change from Mon Dec 2 15:32:15 1996.
The stream is private and usages outside glibc don't care about
reentrancy.
* io/fts.c: Likewise.
* io/ftw.c: Likewise.
* sysdeps/posix/getcwd.c: Likewise.
* sysdeps/posix/ttyname.c: Likewise.
* sysdeps/posix/ttyname_r.c: Likewise.
* sysdeps/posix/glob.c: Likewise.
* libio/iovsprintf.c: Add cast to prevent warning.
* libio/iovsscanf.c: Likewise.
* libio/libioP.h: Define mmap to __mmap and munmap to __munmap
to keep namespace clean.
* new-malloc/malloc.c: Update to last version from Wolfram Gloger.
Add hooks and check functions from old GNU malloc.
* new-malloc/malloc.h: Likewise.
* nis/ypclnt.c: Remove prototype for xdr_free.
* snrpc/rpc/xdr.h: Add prototype for xdr_free.
* manual/nss.texi: Correct description of default values and don't
meantion NSS as an add-on.

"compat [NOTFOUND=return] files".
* nss/pwd-lookup.c: Likewise.
* nss/spwd-lookup.c: Likewise.
* nss/network-lookup.c: Correct default to
"dns [!UNAVAIL=return] files".
* nss/nsswitch.c: Change default-default value to "nis
[NOTFOUND=return] files" since compat is only available for group,
passwd, and shadow.
* stdlib/on_exit.c (on_exit): Rename to __on_exit and make old name
a weak alias.
* stdlib/stdlib.h: Add prototype for __on_exit.
* sysdeps/unix/sysv/linux/schedbits.h: Add prototype for __clone.
* time/Makefile: Undo change from Sun Dec 8 06:56:49 1996.
The new malloc now has mcheck.
* time/ap.c: Likewise.
* time/tzset.c (__tzset): Rename to __tzset_internal.
(tzset): Rename to __tzset. Make tzset a weak alias for __tzset.
* time/localtime.c: Use __tzset_internal not __tzset.
* time/strftime.c [_LIBC]: Define tzname as __tzname and tzset
as __tzset to prevent namespace pollution.
* wctype/iswctype.h (icwctype): Rename to __iswctype. Make iswctype
a weak alias of __iswctype.
* wctype/wctype.h: Add prototype for __iswctype.
(iswalnum, iswalpha, iswcntrl, iswdigit, iswlower, iswgraph,
iswprint, iswpunct, iswspace, iswupper, iswxdigit, iswblank):
Use __iswctype for the test, not iswctype.

(struct hurd_signal_preemptor.preemptor, _hurdsig_preemptors),
hurd/hurd/signal.h (struct hurd_sigstate.preemptors),
hurd/hurdfault.c, hurd/hurdfault.h (_hurdsig_fault_preemptor),
hurd/hurdsig.c (_hurdsig_preempters):
Renamed to fix spelling from `preempter' to `preemptor'.
All uses changed.
1996-12-15 Paul Eggert <eggert@twinsun.com>
* ctime.c (ctime): Return asctime (localtime (t)), as the C
standard requires.
Tue Dec 17 02:05:48 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* sysdeps/mach/libc-lock.h (__libc_lock_trylock): Invert return
value because Mach/cthreads uses the opposite convention from
Posix/glibc.
Mon Dec 16 22:41:01 1996 Ulrich Drepper <drepper@cygnus.com>
* stdio-common/fcloseall.c: Correct test of already_called.

defined, else XTABS.
(CEOL, CSTATUS): Use _POSIX_VDISABLE if defined.
Sun Dec 15 11:56:19 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/unix/sysv/linux/m68k/mremap.S: New file.

(HEADER_SIZE, HEADER_NEXT, HEADER_FREE, HEADER_CHECK): New macros.
