Can you show the error you got, and maybe also a small example how you got it? I'm not sure I fully understand otherwise. Normally, AC_DEFUN under m4_ifndef should work ok. Hmm, you might want to move the AC_DEFUN to a new line, as aclocal essentially greps for it. With m4_define, you need to ensure yourself that the .m4 file you put this in is included in aclocal.m4 (or configure.ac). Cheers, Ralf
