malloc argument is size_t, not unsigned long and so malloc is called in that
case (assuming unsigned long is wider than size_t) with argument 0, not 65536,
so there is nothing to warn about.

Right, thanks.
I'll just submit a patch for gcc.dg/Walloc-size-larger-than-{4,5,6,7}.c to
require "size32plus" then.
