It shows Bb6+ with mate in 16?!  However, when I continue adding moves the mate
total doesn't go down consistently, e.g. it is still mate in 16 for White's next
move.  Surprisingly, Gambit Tiger 2.0 shows similar behaviour.  It also says
Bb6+ with mate in 16, but it's total doesn't drop by one every move either.
Fritz7 says Bb6+ with mate in 22; its total does drop consistently.

I didn't pay too much attention to this initially.  My main point was to show
that the position is not drawn, and that White can win.
