	Try to force a function always to be inlined. More...
#define	P99_LIKELY(...)   P99_EXPECT(!!(__VA_ARGS__), 1)

#define	P99_MACRO_END(...)   extern void P99_PASTE(p00_harmless_declaration_, __VA_ARGS__)(void)
	A meta macro that forces the addition of a semicolon after a call to the macro that it terminates. More...

#define	P99_SETJMP_INLINE(NAME)   P99_WEAK(NAME)
#define	P99_STRINGIFY(...)   P00_STRINGIFY(__VA_ARGS__)
