False.  I have already explained why, with references to K&R and an
old X3J11 draft.

I agree that this is considerably better in practice.  In fact, I
would not at all mind a compiler that gave warnings whenever an
unsuffixed constant did not fit in an integer and was promoted to
long (or unsigned long for `U' suffixed and hex and octal constants,
per X3J11).
