I don't know how to determine what "such cases" are. In the case at
hand, Jari has a network filesystem that is configured in such a way
that the uid/gid of a file can't be determined by standard system calls.
As explained on the Cygwin list, he can set up his /etc/passwd and
/etc/group to work around this. [He has to map the fake SID returned by
Samba to a real one.] If he doesn't want to do that, I think it would
clearly be wrong for euidaccess to return success.
Maybe check_writable could be a little more lenient, but I'm not sure
what the implications of that would be.
