update from main archive 961217 Wed Dec 18 03:31:58 1996 Ulrich Drepper <drepper@cygnus.com> * 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. * nss/grp-lookup.c: Provide default value as "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. 1996-12-16 Paul Eggert <eggert@twinsun.com> * hurd/hurd/sigpreempt.h (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. Reported by Thomas Bushnell, n/BSG. Mon Dec 16 14:52:07 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * mach/lock-intern.h (__mutex_try_lock): New function. Sun Dec 15 16:33:44 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * termios/sys/ttydefaults.h (TTYDEF_OFLAG): Only use OXTABS if 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. * sysdeps/unix/sysv/linux/m68k/Dist: Distribute it. * sysdeps/unix/sysv/linux/m68k/Makefile (sysdep_routines): Add mremap.
