Another ICE (was Re: Portable bitwise operations library)

[Alice Osako]

I've copied the M2bsk code over as Benjamin Kowarsch suggested, and 
got... another internal compiler error.

To say that this is becoming frustrating would be an understatement.

Worse, when I try to build GM2 for 14.x rather than 13.x, it also gets 
an ICE when building the ISO libraries.
