Autoconf finds a working version of GNU m4 as part of its installation
process.  On your machine, it must have found that gm4 was the correct
name for the GNU m4 that was installed at the time you configured
autoconf.  Alternatives to your symlink proposal, which are somewhat more
kosher for system maintainers, would be either reconfiguring and
reinstalling autoconf after you installed the more recent GNU m4, or using
the --program-prefix=g option of m4's configure script to install m4 as gm4.

But Fernando was correct, none of the above paragraph had anything to do
with his bug.
