I agree with that, but ...

| +#define _FPOS_OVERFLOW(pos) ((pos) < LONG_MIN || (pos) > LONG_MAX)
That evaluates its arg 0, 1 or 2 times -- 0 if you're right and the wole
thing is sometimes optimised away, 1 if the value is < LONG_MIN, and twice
(most commonly) otherwise.
Macros that act like that without a very good reason are pure evil.
