Re: [RH143852] autoconf AC_CHECK_TYPE() macro generates compiler warnings

[Paul Eggert]

Thanks for reporting that.  I installed this fix.

        * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C)): Declare longval and
        ulongval to be static, to avoid unwanted GCC warning.  Problem
        reported by Michael Jennings via Daniel Reed; see
        <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
