+       Undo most of the 2007-02-03 change, switching to the strcase module
+       now that gnulib strcase has been fixed.
+       * bootstrap.conf (gnulib_modules): Remove c-strcase.  Add strcase.
+       * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
+       c-strcasecomp.c, c-strncasecmp.c.  Add strcasecmp.c, strncasecmp.c
+       * m4/.cvsignore: Add strcase.m4.
+       * src/getargs.c: Revert 2007-02-03 change, as follows.
+       Don't include c-strcase.h.
+       (language_argmatch): Use strcasecmp rather than c_strcasecmp.
+       strcasecmp has "unspecified behavior" outside the POSIX locale,
+       but it works fine in practice if at least one argument is ASCII,
+       as is the case in Bison.

        * tests/java.at: Skip tests if only one of javac/java is present.
