	Change name of _NL_CTYPE_CODESET_NAME to "charmap".
	* locale/localeinfo.h (enum value_type): Add stringlist.
	* locale/programs/locale.c (show_info): Handle stringlist.

	* locale/programs/charmap.c (charmap_read): If charmap file is not
	using the given name try to find it by looking through all available
	charmap files and compare the code set name.
	* locale/programs/locale.c (write_charmaps): Also print names of
	charset in <code_set_name> fields in the files.

	* elf/ldd.bash.in: Correct translatable strings.

	* posix/TESTS: Add some more tests for character class matching.
	* posix/regex.c: Merge with GNU awk version.
	(regex_compile): Use ISO C/amend 1 functions for character class
	handling.
	* posix/regex.h: Merge with GNU awk version.

	* posix/getopt.c: Declare as master copies.
	* posix/getopt1.c: Likewise.
	* posix/getopt.h: Likewise.

	* sysdeps/unix/sysv/linux/sys/mount.h: Add definitions for option
	value to mount functions.
	Patch by a sun <asun@zoology.washington.edu>.

	* stdio-common/bug4.c (main): Use /tmp/bug4.test for concurrency
	with other tests.
	* sunrpc/svc_run.c (svc_exit): New, defined.
	(svc_run): Test for svc_stop variable.
	* sysdeps/m68k/s_cexp.c: Rewritten.
