1997-02-02 00:39 Ulrich Drepper <drepper@cygnus.com> * dirent/dirent.h: Add description _DIRENT_HAVE_D_TYPE. 1997-02-01 17:04 Philip Blundell <pjb27@cam.ac.uk> * inet/netinet/ip.h (MAX_IPOPTLEN): Add definition. 1997-02-01 17:00 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/socketbits.h: Add definition of cmsghdr structure plus related macros. * sysdeps/unix/sysv/linux/cmsg_nxthdr.c: New file. * sysdeps/unix/sysv/linux/Makefile [$(subdir)=socket] (sysdep_routines): Add cmsg_nxthdr. * sysdeps/unix/sysv/linux/Dist: Add cmsg_nxthdr.c. Suggested by Philip Blundell <pjb27@cam.ac.uk>. 1997-02-01 12:34 Ulrich Drepper <drepper@cygnus.com> * time/strftime.c: Define _strftime_copytm without protecting arguments which breaks the definition. 1997-02-01 03:31 Thorsten Kukuk <kukuk@weber.uni-paderborn.de> * nis/rpcsvc/yp_prot.h: Move definition of yppushresp_xfr after definition of type for element. 1997-02-01 03:28 Philip Blundell <pjb27@cam.ac.uk> * sydsdeps/unix/sysv/linux/netinet/in.h: Add IPv6 related IPPROTO_* constants. 1997-02-01 03:09 H.J. Lu <hjl@lucon.org> * Makefile: Pass PARALLELMFLAGS to sub-makes. * Makefile.in: Mention PARALLELMFLAGS and pass to main Makefile. 1997-01-31 Paul Eggert <eggert@twinsun.com> * time/mktime.c (HAVE_LIMITS_H, HAVE_LOCALTIME_R, STDC_HEADERS): Define if _LIBC is defined. <limits.h>: Include if HAVE_LIMITS_H instead of if __STDC__ || __GNU_LIBRARY__ || STDC_HEADERS. <stdlib.h>: Similarly, include if STDC_HEADERS. (localtime_r): Redo #ifdef to make it clear that glibc has localtime_r now. 1997-02-29 20:08 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sunrpc/Makefile ($(objpfx)rpcsvc/%.h, $(objpfx)x%.c): Use stamp file to avoid unnecessary recompilation. 1997-01-29 19:33 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * Makefile: Set install-others, not install_others. (before-compile): Use += to preserve previous value. ($(inst_includedir)/gnu/lib-names.h): Remove obsolete comment and fix dependency name. ($(objpfx)lib-names.h): Remove rule. * Makeconfig ($(common-objpfx)gnu/lib-names.h): Generate it here, with correct name, using an intermediate stamp file. (common-generated): Add gnu/lib-names.h. (before-compile): Add $(common-objpfx)gnu/lib-names.h. 1997-01-30 18:29 Richard Henderson <richard@atheist.tamu.edu> * malloc/malloc.c (MAGICBYTE): Use cast to size_t instead of unsigned to prevent warnings on 64 bit systems. Reported by Paul Wouters <paul@xtdnet.nl>. * sysdeps/alpha/dl-machine.h: Revert check for broken gas. By default we assume it works.
