	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.
