Of course, only autoconf should appear initially (see below); then as you
send patches adding the next tools, update the list accordingly.

The versions in the TODO are the strictly required versions, and have been
validated (sort of). So stick with those versions.

First patch with the bin-override.
Second patch with the infrastuture and autoconf (as you did so far).
Then one patch for each other tool.

Yes. If you are using mqueue, then you can "guard" patches. I have never
played with that, however.

If you're not using mqueue, then you could use email -r rev1:rev2 to send
all changesets from revision rev1 to revision rev2 (both inclusive), which
you can also do with mqueu, btw).

But please send all patches, so we have a correct sequence to apply.

Don't worry, the round-trips needed to review patches are not regarded as
spamming! :-) If we did in fact have, say, 10 or more in a 1-hour time,
then it could have been. But we'd have gone private long before that! :-)
