Accept a numeric argument. * tests/test-mbscasecmp-4.sh: Renamed from tests/test-mbscasecmp.sh. * tests/test-mbscasecmp-3.sh: New file, based on tests/test-mbmemcasecmp-3.sh. * modules/mbscasecmp-tests (Files): Update after rename. Add locale-en.m4, locale-fr.m4. (configure.ac): Invoke gt_LOCALE_EN_UTF8, gt_LOCALE_FR_UTF8. (Makefile.am): Arrange to run test-mbscasecmp-3.sh, test-mbscasecmp-4.sh, instead of test-mbscasecmp.sh.
