Actually, it seems ExtUtils::CBuilder is currently not doing this correctly
(it only passes the basename to mod2fname). Module::Build contains a
workaround that does do the right thing, which is why no one noticed this
before.
I *really* hate how just about any feature in ExtUtils::CBuilder that isn't
used by Module::Build can be assumed to be broken or unusable on some
non-Linux-like platform (unless someone fixed it in the past couple of
years), if not all of them.
