The macro could also be called from another macro, living in aclocal.m4
or another macro file.  autoconf supports --trace for half a decade now
to find such things out correctly, and autoreconf even uses that method
(in the correct order of running aclocal first to find the set of
interesting files).

Just a thought.  I don't want to disturb fragile grepping of
configure.ac (and yes, I know libtoolize does it too; that doesn't make
it any better).
