r23961: Allow SWAT to operate on x86_64 machines.
On machines with a 4 byte int, and a 8 byte pointer, the ESP could would fail.
The problem is that 0 != NULL. 0 is an int (4 bytes) and NULL is a
pointer (8), and this matters critically to varargs functions.
If a 0 was passed as the 'terminating' argument, then only 4 bytes
would be written to the stack, but va_arg(ap, char *) would try and
pull 8, reading uninitalised memory.
