glibc/elf/Makefile
Ulrich Drepper 9afc8a5964 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.
