Can white win?lets c.
At first blush it looks like white could do a nasty thing with a check or two here and there, and then move in to dimantle the pawns at a6 and b5 to allow his white bishop to eat up the last one, which would both attack the king and allow free space for the possiblity of the white pawns converting to queens.
I think I should have used some more periods or semicolons...
