Automake is very good at telling you about incompatibilities while
upgrading. I don't recall Automake misbehaving at run-time due to an
incompatibility, but it is possible that it may have happened before
and I just don't remember.
Upgrading Autoconf is much more of a concern than upgrading Automake.
Unfortunately, newer Automake's require newer Autoconfs.
