--- Comment #4 from Richard Yao <ryao at gentoo dot org> ---
How would GCC "reject all programs" without emitting an error? If there is some
other way, it is not being done as GCC emits assembly that assembles and links
without a problem. Rejecting the program should not allow things to go so far.
If `-pedantic` does not cause programs to be rejected under any circumstance,
then the documentation is wrong.
