The included method of determining the host platform in the androideabi would not match to windows if RUBY_PLATFORM returned mingw, wince, or emx. As an added pre-caution, using a case statement with regexp matching will better determine the host platform since it won't be case sensitive and for windows is set to match more specifially than just "win".
