+       Fix unportable use of bit-fields.
+       * lib/unicase/special-casing.h (struct special_casing_rule): Change the
+       bit-field type from 'int' to 'signed int'. Otherwise Solaris cc,
+       AIX xlc, and OSF/1 cc interpret it as 'unsigned int'.
+

+
        Avoid test failures on AIX and OSF/1.
        * tests/unicase/test-u8-casefold.c (check): Account for the possibility
        that malloc(0) = NULL.
