Greetings, Cygwin!

Note the single leading slash.
Most likely, the program performs manual "normalization" of the path, which is
not POSIX-compatible.
POSIX explicitly declare that double leading slash is a special case, and its
behavior is defined by the underlying system.
If 2.0 would exhibit the same behavior, it is worth reporting upstream.

Indeed.

Try doubling the backslashes.
