Update.
1998-03-30 12:53 Ulrich Drepper <drepper@cygnus.com> * sysdeps/i386/i486/bits/string.h (__strcat_c) [__i686__]: Correct scanning for \0. (__strncat_g): Add i686 specific code. 1998-03-30 Andreas Jaeger <aj@arthur.rhein-neckar.de> * manual/install.texi (Reporting Bugs): Ask to include section names in reports. 1998-03-28 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/Makefile ($(objpfx)syscall-%.h): Emit guard against direct inclusion. 1998-03-28 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> Rework support for libc_nonshared.a: * Makeconfig (object-suffixes-for-libc): New variable. * Rules: Remove handling of static-only and shared-only routines. * Makerules: Handle them here instead. Use object-suffixes-for-libc instead of object-suffixes when dealing with libc objects. (object-suffixes-for-rules): Remove variable. (elide-routines.oS): Elide all routines except static-only routines. ($(objpfx)stamp.oS): Special rule for when static-only-routines is empty. (installed-libcs): Remove special case for .oS. (rmobjs): Likewise. 1998-03-28 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * Makefile (do-collate-test, do-xfrm-test, do-tst-fmon, do-tst-rpmatch): New targets. (test): Use them. (install-locales): Ignore comment lines. 1998-03-28 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/Makefile ($(objpfx)ld.so): Depend on version script. ($(objpfx)trusted-dirs.h): Depend also on $(..)Makeconfig. ($(objpfx)rtldtbl.h): Likewise. (CPPFLAGS-dl-load.c): Fix reference to object directory. 1998-03-30 09:36 Ulrich Drepper <drepper@cygnus.com> * manual/string.texi (Finding Tokens in a String): Extend strsep description and correct example. 1998-03-28 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * manual/socket.texi: Remove misguided explicit line breaks and fix the formatting problem instead by reformulating the paragraphs. * manual/filesys.texi: Likewise. * manual/conf.texi: Likewise. Don't typeset table with index fonts, that looks worse than a minimally overfull line. 1998-03-28 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * nscd/Makefile (nscd-modules): Move definition outside of conditional. * pwd/Makefile: Use have-thread-library to test for thread library. 1998-03-30 Andreas Jaeger <aj@arthur.rhein-neckar.de> * nss/getXXent_r.c (INTERNAL): Remove unused variable current_nip. * iconvdata/uhc.c (gconv): Remove unused variable idx. 1998-03-30 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/Dist: Add lddlibc4.c.
