Update.
1998-10-02 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/unix/sysv/linux/sys/swap.h (SWAP_FLAG_PREFER, SWAP_FLAG_PRIO_MASK,SWAP_FLAG_PRIO_SHIFT): Added. Remove inclusion of <linux/swap.h>. 1998-10-05 Ulrich Drepper <drepper@cygnus.com> * io/sys/stat.h: Use __P in definitions of inline stat functions so that they match the declaration. 1998-10-02 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/unix/sysv/linux/sys/quota.h (Q_RSQUASH): Added. 1998-10-02 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/unix/sysv/linux/sys/acct.h: Bring in sync with current linux 2.1 version. 1998-10-02 Philip Blundell <pb@nexus.co.uk> * sysdeps/arm/dl-machine.h: Fix typo in last change. * sysdeps/arm/bits/huge_val.h: New file. 1998-10-02 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/unix/sysv/linux/sys/reboot.h (RB_POWER_OFF): Added. * sysdeps/unix/sysv/linux/sys/ptrace.h (PTRACE_SYSCALL): Add define. 1998-10-05 Ulrich Drepper <drepper@cygnus.com> * sysdeps/posix/getcwd.c (__getcwd): Use temporary variable to store result of realloc instead of using BUF. 1998-10-04 Andreas Jaeger <aj@arthur.rhein-neckar.de> * misc/sgtty.h (_SGTTY_H): Correct spelling. Reported by Rouben Rostamian <rostamian@umbc.edu> [PR libc/817]. 1998-10-04 Andreas Jaeger <aj@arthur.rhein-neckar.de> * manual/memory.texi (Obstacks): Document obstack_alloc_failed_handler usage. * malloc/obstack.h: Enhance comment about obstack_alloc_failed_handler usage. * malloc/obstack.c: Likewise. 1998-10-05 Ulrich Drepper <drepper@cygnus.com> * misc/sys/cdefs.h (__extension__): Define as empty if no gcc or gcc before 2.8 is used. 1998-10-01 Philip Blundell <pb@nexus.co.uk> * sysdeps/arm/machine-gmon.h: Correct args to mcount(). Patch from Scott Bambrough. * sysdeps/unix/sysv/linux/arm/register-dump.h: New file. * libio/libioP.h (FILEBUF_LITERAL) [! _IO_MTSAFE_IO]: Don't include the lock member. 1998-09-03 Philip Blundell <pb@nexus.co.uk> * sysdeps/arm/fpu/__longjmp.S: Cope with fussy assembler. 1998-09-29 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * string/bits/string2.h (__string2_1bptr_p): Don't use a statement expression. (__mempcpy, strcpy, __stpcpy, strcmp, strcspn, strspn, strpbrk, __strsep): Greatly reduce size of expansion by combining common expressions. (__mempcpy_small, __strcpy_small, __stpcpy_small): Convert to inline function. (__mempcpy_args, __strcpy_args, __stpcpy_args): New macros, used by the above definitions. 1998-09-27 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/unix/sysv/linux/powerpc/bits/ipc.h: New file, use correct struct ipc_perm definition. 1998-09-29 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * nis/ypclnt.c (yp_all): Close UDP socket und give CLIENT handle free. * sysdeps/unix/sysv/linux/alpha/ioperm.c: List Ruffian in platforms[]. * sysdeps/unix/sysv/linux/net/if_shaper.h: New file.
