I don't believe the standard requires the following to be rejected, but as a QOI
issue I believe it should be. The debatable point is whether you believe the
composite of the first two is specified by a function definition; if you do then
you must reject. GCC rejects it if the order of the first two is switched.
void r(x) int (*x)[2]; {}
void r();
void r(int (*x)[3]); /* Ideally rejected. */
Flags are e.g. -Wall -std=c99 -pedantic
