        * NEWS: Remove AC_CACHE_CHECK_INT.
        * doc/autoconf.texi (Caching Results): Likewise.
        * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
        AC_CACHE_CHECK_INT, since it's no longer public.
        * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
        * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
