m4 is a PITA portability-wise, at least when using it to the extend
autoconf does :(

Though I doubt we would be hit by the issues autoconf is facing (In most
cases exceeded buffers - Other problems, such as limitations of the m4
language will probably not hit), I would prefer if we could get away
without using it 

[I am inclined to think m4 would have been dead for quite a while if
autoconf and sendmail weren't using it;)]

Yes, Erik? ;)

Right, autoconf requires gm4 and therefore probably already is available
in most U+ix-ish environments.
