Cygcheck is a native Windows executable and thus does not use Cygwin's
path handling (in contrast to md5sum, for instance).  Rather it uses a
home grown version and this in turn has a bug when checking the cygdrive
prefix against the incoming path.  Everything goes, just not '/' alone.

I pushed a fix and uploaded new developer snapshots to
https://cygwin.de/snapshots/

Please give them a try.


Thanks,
