	(rpath-link): Add nisobjdir.
	Patch by Sven Verdoolaege <skimo@kotnet.org>.

	* elf/Makefile: Pretty print.
	* elf/dl-lookup.c: Include unistd.h.
	* elf/dl-runtime.c: Likewise.

	* localedata/Makefile (test-srcs): Add tst-rpmatch.
	(distribute): Add tst-rpmatch.sh.
	(tests): Add tst-rpmatch to dependency list and run tst-rpmatch.sh.

	New tests for rpmatch function by
	Jochen Hein <jochen.hein@delphi.central.de>.
	* localedata/tst-rpmatch.c: New file.
	* localedata/tst-rpmatch.sh: New file.

	* localedata/locales/de_DE: Correct yesexpr and noexpr.
	* localedata/locales/de_AT: Likewise.

	* posix/getopt.c: Update contact address.
	* posix/getopt1.c: Pretty print.

	* sysdeps/generic/libc-start.c: Do most of the initialization now
	here instead of in start.S.
	* sysdeps/unix/sysv/linux/libc-start.c: Likewise.
	* sysdeps/i386/elf/start.S: Remove most of the initialization code.

	* sysdeps/unix/sysv/linux/i386/profil-counter.h: No need for
	profil_counter to be public.

	* posix/wordexp.c (parse_arith): Now works for negative numbers too.
	(parse_param): Coded parameter length expansion (${#var}).
	(parse_param): Handling for "=", "+", "-", and the ":" versions added.
	(parse_param): Cleaned up (fixed) error handling.

	* posix/wordexp-test.c: IFS now includes non-whitespace character
	(comma).  Added more tests.
