glibc/posix/getopt.h
Ulrich Drepper 51702635af Update.
* locale/categories.def: Change type of _NL_CTYPE_CLASS_NAMES and
	_NL_CTYPE_MAP_NAMES field to stringlist.
	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.
	* sysdeps/m68k/s_cexpf.c: Likewise.

/* Describe the long-named options requested by the application.
The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector
of `struct option' terminated by an element containing a name which is
zero.
The field `has_arg' is:
no_argument (or 0) if the option does not take an argument,
required_argument (or 1) if the option requires an argument,
optional_argument (or 2) if the option takes an optional argument.
If the field `flag' is not NULL, it points to a variable that is set
to the value given in the field `val' when the option is found, but
left unchanged if the option is not found.
To have a long-named option do something other than set an `int' to
a compiled-in constant, such as set a value from `optarg', set the
option's `flag' field to zero and its `val' field to a nonzero
value (the equivalent single-letter option character, if there is
one). For long options that have a zero `flag' field, `getopt'
returns the contents of the `val' field. */
