1997-01-21 Paul Eggert <eggert@twinsun.com> * posix/getopt.c (_getopt_internal): Return -1, not EOF, when args are exhausted; this is required by POSIX.2. * catgets/gencat.c, db/makedb.c, locale/programs/locale.c, locale/programs/localedef.c, manual/examples/subopt.c, posix/getopt.c, posix/getopt1.c, stdio-common/bug4.c, sunrpc/rpcinfo.c (main): Check getopt return value against -1, not EOF. Tue Jan 21 23:10:40 1997 Ulrich Drepper <drepper@cygnus.com> * version.h (VERSION): Bump to 1.102. * sysdeps/unix/sysv/linux/alpha/Dist: Add kernel_sigaction.h. * elf/Makefile: Don't use CFLAGS-dl-load.c, but instead CPPFLAGS-dl-load.c so that dependencies can be determined correctly. * elf/dl-load.c: Fix comment. * time/Banner: New file. * time/Makefile (distribute): Add Banner. Update from ADO tzcode1997a and tzdata1997a. * time/antarctica: Update. * time/australia: Update. * time/zdump.c: Update. * time/zic.c: Update. * time/zone.tab: Update. Mon Jan 20 08:38:32 1997 H.J. Lu <hjl@gnu.ai.mit.edu> * config.make.in (has-ldconfig): New variable. * configure, configure.in (has_ldconfig): New substitute. * sysdeps/unix/sysv/linux/configure.in (has_ldconfig): New, check if $srcdir/elf/ldconfig.c exists. * Makeconfig (rootsbindir): New, default as $(exec_prefix)/sbin. (rtld-version-installed-name): New, default as ld-$(version).so. * Makefile (install): Call `$(common-objpfx)elf/ldconfig -d' only if $(cross-compiling) is no and $(build-shared) is yes. * Makerules (make-shlib-link): New macro. ($(slibdir)/libfoo.so.$(libfoo.so-version)): Use $(make-shlib-link) for symlink. (install-rootsbin, install-rootsbin-nosubdir): New. (install-no-libc.a-nosubdir): Add install-rootsbin-nosubdir. * Rules (others): Add $(install-rootsbin). * config.make.in (rootsbindir): New. * configure, configure.in (libc_cv_rootsbindir): New substitute. * elf/Makefile (others, install-rootsbin): New, set to ldconfig. (+link): New for static linking. ($(slibdir)/$(rtld-version-installed-name)): New. ($(slibdir)/$(rtld-installed-name)): Depend on $(slibdir)/$(rtld-version-installed-name) and use $(make-shlib-link) for symlink. * sunrpc/xdr.c (xdr_string): Return FALSE if sp == NULL while XDR_ENCODE. * sysdeps/unix/sysv/linux/a.out.h: Use #include_next for glibc internals. * sysdeps/unix/sysv/linux/configure.in (libc_cv_rootsbindir): New, set to "/sbin" if "$prefix" == "/usr". Tue Jan 21 13:38:39 1997 Ulrich Drepper <drepper@cygnus.com> * Makefile (distribute): Add glibcbug.in. Reported by Philip Blundell <pjb27@cam.ac.uk>. * elf/Makefile ($(objpfx)trusted-dirs.h): Create elf/ subdir in build directory if necessary. Reported by marcus@shannon.sysc.pdx.edu (Marcus G. Daniels).
