I guess the sizeof comparison would not be necessary since the
condition should never meet with 64-bit longs.
Unless it's in a code fragment that's used only on machines with
<64-bit longs, it will; X runs on systems with 64-bit longs.
I meant the condition "dpy->request < dpy->xcb_last_flushed" should not
meet on systems with 64-bit longs (at least not until the 64-bit wrap).
So the "sizeof(uint64_t) > sizeof(unsigned long)" would not be
necessary. It would just increase the overhead on <64-bit systems.
And if it does, something is wrong anyway (from my understanding).
After all this is the trigger of the bug.
Does anyone know whether the bug triggers on systems with 64-bit longs?
I would say no, because there is no 32-bit to wrap. But who knows, I
have not tried it.
