Make isn't the problem.  As the system currently stands, when
something is modified it is recommended to delete the build tree and
start afresh -- doing otherwise only brings false positives (or
negatives depending on how you count).  I've been bitten enough to
know that for the moment, it is always the "first time".

I doubt I'm alone; or if I'm alone, I doubt I'll stay alone for long
time.  Unless Axiom stays with only 2 "coders", I suspect this issue
needs to be addressed somehow. I have some students who will be poking at
various parts of the system.  I would hate they spend most of their
time waiting for the compiler.
