  Yes, any program that is a), b) and includes one of the numerous system headers that directly define 'size_t' (and thus directly or indirectly include <sys/types.h>).

  Well, bugs are usually a kind of impractical thing? :-)

  No, since we can't be sure <stddef.h> is included in front of other system headers.
