Update.

2000-09-06  Ulrich Drepper  <drepper@redhat.com>

	* posix/getopt.c (_getopt_internal): Don't recognize an option
	name as ambiguous if it's a prefix for more than one name but the
	other struct option values are identical.

	* posix/tstgetopt.c: Add test for improved ambiguity recognition.
	Don't depend on visual inspection of the output file to recognize
	errors.
	* posix/Makefile (tstgetopt-ARGS): Add a few more parameters.
