setcc() in math-emu is written as a gcc extension statement expression
macro that returns a value. However, it's not used that way and it's not
needed like that, so just make it a do-while non-extension macro so that we
don't use an extension when it's not needed.

-#define setcc(cc) ({ \
- partial_status &= ~(SW_C0|SW_C1|SW_C2|SW_C3); \
- partial_status |= (cc) & (SW_C0|SW_C1|SW_C2|SW_C3); })

+}
... seems to contradict the implementation. No "do-while" here.
I hope this helps,
Jochen
