I think POSIX 2001 allowed that, but with the openat() and friends added
in POSIX 2008, I think that POSIX now prohibits this implementation, and
requires that dirfd work rather than giving up with ENOTSUP.  At any
rate, gnulib should try and strive for returning a non-negative value,
even if POSIX has a loophole that would allow -1.
