[PATCH] i386: avoid gcc extension

Browse Source 
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 inline function so that we
don't use an extension when it's not needed.
