I just had a look, and could find exactly what advice you'd like.
Also, we are working on 2.53.  If you need special features, please
let us help you by specifying them!  And finally, defn is very
different from bind :)  I'd love to have a bind in M4, I suspect we'd
have serious performance improvements.

Err... Using CVS Autoconf:

/tmp % cat script.4s                                             nostromo 19:31
AS_INIT
AS_SHELL_SANITIZE
echo $LINENO
/tmp % autom4te -l m4sh script.4s -o script                      nostromo 19:31
/tmp % ./script                                                  nostromo 19:31
