Done. The behaviour is perfectly valid.
- "//foo/bar" requires to access the path, which in turn triggers an SMB
request on the wire. This takes a couple of seconds within Windows
itself, even if the DNS request returns immediately that the server
doesn't exist. NetBIOS? Anyway, there's nothing Cygwin can do about
it.
- "//foo" is a virtual path, valid only in Cygwin. You can't access
"\\foo" in the Win32 API using file or directory access functions. It
just doesn't exist as a path. UNC paths are only valid with at least
two path components as in "\\server\share". Since "//foo" is a
virtual path, there's no Win32 equivalent. So, from the Windows
perspective there's "No such file or directory".
