Yes, this is right, XID is unsigned long

I fear this is not true. I have found everywhere that for 64 bits,
pointers and long are 64 bits, and I did not find an option to force
long to be 32 bits in gcc. (-m32 is not an answer as it will compile a
32bit code)

We can say that, except I am quite surprise of your "default" compiler
bahaviour, are you sure of that? With gcc?
