Some other random points slightly related to this:
- Patches wouldn't normally patch the generated configure script, so
the git repo wouldn't need to store the generated code in order to
be useful as a store of patches. I have used this git system to
manage patches which are then applied on top of the pristine
upstream tarball and it has always worked fine.
- If you did patch the configure script you could add the generated
files to git. Or use the exploded tree git to store the tarball.
- In any case I don't want to force anyone to use this system. It's
just a way to consolidate the duplicated work that at least 5 teams
are currently using to manage patches. You can quite happily keep
using your own way of managing patches if you don't like it.
- configure.ac that depends on specific old versions of autoconf is,
as a rule of thumb, broken.
