POSIX requires open() to work on directories, and GNU find has been using
open() and not opendir() for some time now (although with the recent
switch in find to use gnulib's fts module, that will change in find
4.3.x.)  The only bug that I am aware of that was reported to find where
open(dir) failed was due to a cygwin bug which has since been fixed in
cygwin.  If, in fact, we do find a non-compliant system where open() fails
on dirs, it might be better if that system were given a gnulib module that
implemented a wrapper around open which calls stat then open/opendir as
needed, rather than penalizing the majority of compliant systems.

Nope - FSF requires assignment of copyright, not abandonment.
