As far as the C standard is concerned, the behavior is undefined.
Depending on the calling convention, main(42) *might* do something
equivalent to setting argc (probably not argv[0]) to 42, and probably
putting garbage into the argv pointer -- but since main's definition
doesn't declare argc, it can't refer to it anyway. There is no
argc or argv in this case.
