Various tests do things which we want to detect at runtime, like ignoring the result of malloc or doing a deliberate impossibly large allocation or operations that would result in overflowing or truncated strings, that generate a warning from gcc. In once case, mq_setattr called with new and old attrs overlapping, this was explicitly fixed, in others -Wno-foobar was added to silence the warning. This is safe even for older gcc, since a compiler will ignore any -Wno-foobar they don't know about - since they do know they won't warn for foobar.
