Also, I'm pretty sure I've seen projects using macros that start
with AC_ (orbit has one, I think).  Maybe they do this for macros
they want to propose for inclusion in autoconf.  Will autoconf
choke on these, too?

(I wonder how to find all of these... I suppose searching through
the debian source tree and bsd port system for all instances of 
AC_DEFINE_UNQUOTED might be a good start...)
