A-ha.  Thanks for that additional information.  The problem is that any 
macro defined via AC_DEFUN includes a prologue that _requires_ that 
AC_INIT has already been called.

If you s/AC_DEFUN/m4_define/ in your my_init.m4 file, that should make 
the difference.  The whole point of AC_DEFUN is that it allows macro 
dependency tracing, via things like AC_REQUIRE, but since you don't need 
to do any dependencies on EFL_INIT (that is, no one should be doing 
AC_REQUIRE([EFL_INIT]), it's overkill to use that.  So, by using a 
plain-and-simple m4_define'd macro instead of an overboard AC_DEFUN'd 
macro, I think you can get further.
