Regarding srcdir == builddir, I agree as well. The problem is that
we have to consider the source packaging as well. I don't know it
well enough right now to tell you whether it would work out-of-tree
or not. After all, you're trying to create a package of the sources,
which includes the files that were checked in the repository, but
also some files that are generated by the source-package process.
I wouldn't want to be missing some files by doing it out of tree...
Maybe there is already a way. If there was, I wouldn't mind taking
the approach where srcdir == builddir is no longer supported. This
would allow some simplifications, particularly in the testsuite
area, I believe.
