Without knowing the full details, I'd risk saying that this was not
the best decision. Is there really no way of making d_ino be
consistent with what `stat' returns about the same directory?
In any case, I think removing the member is a solution that is much
worse than the problem: many programs refer to d_ino, but don't
require too much from its contents. These programs will now fail to
compile. I don't think that the goal of educating the maintainers of
Bash and Find (a worthy goal in itself) justifies breaking the other
packages.
If making d_ino consistent with st_ino is impossible, a better way of
dealing with problems in Bash and Find is to make changes in those
packages' sources that are specific to Cygwin.

The immediate fix seems to be to modify the definition of
DIRENTRY_NONEMPTY for Cygwin so that it uses the same trick as on
MS-DOS. (Isn't it sad that Cygwin needs old MS-DOS era tricks?)
