Currently, the internal semantics of AC_DEFUN are that way, that it
does not make sense if the third argument is either empty, or either
'm4_define', or 'm4_pushdef'.

That probably doesn't help you much, but I don't know what better help
to give you, given this information.  Maybe if you have problems, you
could post some code.
