It's the same.

We need 2 things:

1- Check for GNU M4's name and set $(M4) to it.  If it's not found,
    configure should fail.  I guess, configure should also be able
    to accept a pre-set $(M4) environment variable as override.

2- Do something similar with "-lrt", which is giving me a hell of a
    time.  Configure should figure by itself whether it is needed or
    not.

Any idea how tom implement these? :-)
