[autoconf-conversion] Something to start with

[Tom Tromey]

Daniel> I agree with the "at the end" part.  I'd like to suggest this method:
Daniel>   - Rename configure.in to configure.ac in every directory we convert.
Daniel>     Yes, I realize what this does to CVS history.
Daniel>   - Post diffs from configure.in to configure.ac instead of a full
Daniel>     diff.

I don't understand this point.  You mean I should run "diff
configure.in configure.ac" when posting?  Maybe it would be better to
2.57-ize the configure.in (including adding the AC_PREREQ), and then
do the rename as a separate step immediately after.

Daniel> - Make the minimal necessary changes, and we can go pack to
Daniel> prettying it up later.

Definitely.
