Update.
1999-12-18 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/i386/setrlimit.c: Declare local variable result if necessary. * sysdeps/unix/sysv/linux/i386/bits/resource.h: Don't depend on the unreliable kernel headers. * sysdeps/unix/sysv/linux/bits/resource.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/resource.h: Likewise. * sysdeps/unix/sysv/linux/alpha/bits/resource.h: New file. * sysdeps/unix/sysv/linux/mips/bits/resource.h: New file. 1999-12-18 Andreas Jaeger <aj@suse.de> * config.make.in (datadir): Added. Closes PR libc/1491. Patch by dervishd@jazzfree.com. 1999-12-18 Andreas Jaeger <aj@suse.de> * sysdeps/unix/sysv/linux/ftruncate64.c (ftruncate64): Save and set errno. * sysdeps/unix/sysv/linux/truncate64.c (truncate64): Likewise. 1999-12-18 Andreas Jaeger <aj@suse.de> * sysdeps/unix/sysv/linux/fxstat64.c: Rewrite to use fstat64 syscall if available. * sysdeps/unix/sysv/linux/lxstat64.c: Likewise for lstat64. * sysdeps/unix/sysv/linux/xstat64.c: Likewise for stat64. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_STAT64_SYSCALL): New. 1999-12-17 Scott Bambrough <scottb@netwinder.org> * sysdeps/arm/dl-machine.h (CLEAR_CACHE): New macro to force a cache flush. * elf/dl-reloc.c (_dl_relocate_object): Add call to flush cache after .text segment fixups. 1999-12-16 Andreas Jaeger <aj@suse.de> * rt/aio.h: Remove erroneous __restrict declarations. 1999-12-18 Ulrich Drepper <drepper@cygnus.com> * scripts/rellns-sh: Find pwd program also in /usr/bin and let shell do the job if it is there neither. Patch by David R. Conrad <drc@adni.net> (PR libc/1485). 1999-12-16 Andreas Jaeger <aj@suse.de> * sysdeps/ieee754/bits/nan.h (NAN): Rename union to avoid duplicate definition with function __nan. Closes PR libc/1487 reported by <diana@kai.com>. * string/bits/string2.h (__strsep): Help gcc optimizing string access.
