Re: [PATCH] math-emu/setcc: avoid gcc extension

From: Segher Boessenkool

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.

Looks fine, except

-#define setcc(cc) ({ \
+#define setcc(cc) do { \
partial_status &= ~(SW_C0|SW_C1|SW_C2|SW_C3); \
- partial_status |= (cc) & (SW_C0|SW_C1|SW_C2|SW_C3); })
+ partial_status |= (cc) & (SW_C0|SW_C1|SW_C2|SW_C3); } \
+ while (0)

closing brace on the "while" line, please.
