[Please describe your issue here]

Recent commit be55b2856b90113f440eb7966a4cadedd69ee5e7
Author: Karl Williamson <khw@cpan.org>
Date:   Sat Nov 18 16:50:48 2017 -0700

    locale.c: Use computed length for U+10FFFF

    The previous commit calculates this and placed the result in a header
    file.  This now uses the calculated value instead of a hard-coded "4",
    which is incorrect on EBCDIC platforms.

introduced the following build warning on my machine:

locale.c:2942:30: warning: comparison of integers of different signs:
'int' and 'unsigned long' [-Wsign-compare]
        is_utf8 = MB_CUR_MAX >= STRLENs(MAX_UNICODE_UTF8);
                  ~~~~~~~~~~ ^  ~~~~~~~~~~~~~~~~~~~~~~~~~
