Do we have any of these? I'd just change AC_DEFUN_ONCE to the meaning
you suggest for AC_DEFUN_IDEMPOTENT, with this further change to its
semantics: if an AC_DEFUN_ONCE is invoked from the toplevel, never warn;
if it is invoked from a macro without AC_REQUIRE, always warn. For 2.65
we can start using AC_DEFUN_ONCE more liberally in autoconf itself
