It'll have to be CPU_CAPS, get_cpu_count() an do on, to be consisten with 
Allegro. Or am I missing something?

In anycase the capabilitiy flags need to be accessible easily via assembly, 
for all those MMX and SSE enabled code inside Allegro, so a function call 
with structs being passed around may not be such a good idea.

However, I'm concerned about multi-cpu computers, especially when one CPU 
has more capabilities than the other (Although I'm not sure such 
combinations can be made). Any ideas on how this works?
