Yes.  Cygwin is not generating device/inode numbers consistently,
when used on a remote share.

However, part of the problem appears to be inherent in SMB (the windows
file sharing protocol).  Also, some underlying filesystems (FAT) do not even
have the concept of an device/inode, so Cygwin has to create one.

Yes, but you may want to put a workaround in Jed when running on Cygwin
to not try and do inode comparisons when building for cygwin.

I think the work around in jed is going to be to not do inode
comparisons when built under Cygwin.
