Just moments after writing that, I was startled to read on another
mailing list that the long-mythical Autoconf 2.50 is released!

We should probably consider updating from autoconf 2.13 as our project
standard to 2.50.  However, I'd recommend waiting till Peter E. returns
from his vacation to see what his opinion about it is.  IIRC, he's been
following that project, which I have not been.
