Yes, that's actually a bug.  The mount code path in Cygwin checks
the path for being a share (i.e. \\server\share\... syntax)

The code, which, incidentally, has only been marginally changed since
its inception pre-2000, is expecting that server name as well as share
name both start with an alphanumeric ASCII char.

That means, right now you can't mount servers and shares starting with
any character other than [0-9a-zA-Z].  D'oh.

I pushed a patch and the Cygwin test release 3.5.0-0.138.g6338d2f24a60
is building while I'm replying.  Should be up in an hour or so.


Thanks,
Corinna
