I just remembered that Fedora builds with srcdir == builddir, at least
when a package maintainer runs "fedpkg local". I do not know if the
actual binary rpm building process does this, or if it happens for
distributions other than Fedora, but I just thought that it would be
So if we do decide to ban srcdir == builddir then this might have some
cost for various distribution maintainers. Although in the long run
it would probably be a good thing.
