64 bit implementation

[Sasha Vasko <sasha aftercode net>]

Hi

Here is a little problem that surfaced when couple guys tried to port 
AfterStep to 64-bit Sun system: It appears that all the XIDs on the 
client side are 64-bit long. Looking at X.h from XFree86 Xlib I see that
indeed client XIDs will be 64-bit unsigned long, but at the same time, 
server should use 32-bit CARD32 XIDs. What appears is that when 64-bit 
IDs on the client are stored in 32 bit variables it produces 
BadDrawable/BadWindow errors. I thought for a moment that problem is in 
endiannes, but AFAIK SPARC systems are all big endian.

Now in the specs we explicitely mention 32-bit values for everything.
Should we change it? I really am clueless about how 64-bit X should be 
treated, so maybe more educated ppl out there can provide some insight.
