We can't do this for wfb, since the pixman accessor functions are 32 bits wide. And we should only do this when long is 64 bits, since otherwise we're on a 32-bit machine and uint64_t would likely be emulated.
Sadly, while this does build, it does not work. The root weave looks correct, but xlogo looks vertically squished and metacity's decs don't show up at all. Probably this is related to the pixman caveat above! So now all you need to do is audit fb for pixman calls and make sure the strides they use are as if FB_SHIFT was 5. (And maybe whatever else is still broken after that's done.)
