By the way, you may be interested in seeing how I was able to use
m4_define and still get aclocal to use my file for gnulib's AC_DEFUN_ONCE
replacement (coupled with an AC_REQUIRE([gl_00GNULIB]) in gnulib-common.m4):
http://git.savannah.gnu.org/cgit/gnulib.git/tree/m4/00gnulib.m4
http://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=fcf62c3d
Yes, I thought this might have been the trick you used:
AC_DEFUN a macro with no expansion in the same file, just to get
aclocal to include it. Way to work around the rules! :-)
Regards,
John
