Thanks! The more granular we can be about disabling specific warnings

Well, hang on; it's also perfectly legal for a malloc implementation
to return NULL for requests of zero bytes. You can access exactly the
number of bytes requested in the allocation; and free(NULL) works as
expected. NULL (0) is also aligned to any size you could want.
