Thanks, but I'm about to send v2.5 to address the issue reported
by Michael Young (adjusting configure{.ac,} only).

Well, the version I've been using to re-generate isn't identical
to yours, but allows easily filtering out and discarding the few
extra differences, which is why I dared to provide a diff for
tools/configure in the first place. IOW if I would commit this
myself, all I would ask that you or someone else using the
"original" autoconf to generate the committed version to double
check.
