Note that I ship a version of configure (and keep one checked in to
git) because I do not trust the autoconf maintainers' ability to
maintain backwards compatibility, having gotten badly burned in the
past.  I am currently using autoconf 2.69, and people who try to rerun
autoconf on some other version of autoconf are venturing into
unsupported territory.  It may work; it may screw up in amazing ways.
Some autoconf macro may silently assume that some feature is present
when it is not, or vice versa.

And if it breaks, you get to keep both pieces.  :-)

that's fine, but it doesn't really matter to this patch -- it should be 
configure.ac and not configure.in.  the version of autoconf you're using 
certainly supports the newer name.

This patch breaks the automatic rebuild of configure if the
configure.ac/configure.in file is modified.  I've fixed it up by
adding the necessary change to MCONFIG.in.
