commit 920a0395ba9fa5949ec87aaf5daa0259da16749d
Author: Stefan Liebler <stli@linux.vnet.ibm.com>

    Use correct signedness in wcsncmp

        [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.
