Since the tag for C++ is called CXX and there is no tag for C,
it would seem more natural to read

  AC_LIBTOOL_TAGS([CXX F77])

I think Bob's suggestion of AC_LIBTOOL_LANGUAGES is better if
you really want to pass language names as arguments.

Maybe this can be simplified to something around the lines of

m4_case([_LT_TAG],
        [C], ,
        [CXX], [...],
        [F77], [...],
        [GCJ], [...],
        [RC], [...],
        [m4_fatal([unsupported tag name: ]"_LT_TAG")])
