[BZ #18206] * wcsmbs/wcsncmp.c (wcsncmp): Compare as wchar_t, not wint_t. Use signed comparision instead of substraction to avoid overflow bug. * localedata/tests-mbwc/tst_wcsncmp.c (tst_wcsncmp): Take the sign of ret. * localedata/tests-mbwc/dat_wcsncmp.c (tst_wcsncmp_loc): Do not expect precise return values. Only the sign matters. * wcsmbs/Makefile (strop-tests): Add wcsncmp. * wcsmbs/test-wcsncmp.c: New File. * string/test-strncmp.c: Add wcsncmp support.
