If we're talking about libtool 1.5, then notice the first thing AC_PROG_LIBTOOL does is an AC_REQUIRE of _AC_PROG_LIBTOOL. :-( You might get the effect you want by having the conditional at the top-level in configure.in, rather than within a macro. Beware of standard macros which then only run under that conditional too.
