I understand the heavy use of fdopendir() in coreutils: on those systems
which implement this function natively, it's a race-free alternative to
opendir(). Therefore I find it reasonable to emulate fdopendir() in gnulib.

But fopen() on a directory? Who does that? If no-one needs that, I would be
satisfied with mentioning the problem under "Portability problems not fixed by
Gnulib" in the doc.
