I am aware of the AC_PREREQs which were put in place by Ian Lance Taylor
a long time ago.  I was told that autoconf has forked.  These newer versions
have not been tested.  I thought that 2.57 was one of these.  I am certainly
not clear on autoconf's versioning numbers - whether 2.5x is really 2.5.x or
if it is 2.5x where 5x > 13?  Regardless, I wouldn't count on an older autoconf
version working either.  You are correct that the prereqs should be updated.
