1. How can i prevent GCC from using a certain segment register? 
   Or doesnt it use all segment registers? (Well, cs for code, ds for data,
   ss for stack, fs for _far stuff... es and gs seem to be unused!)
   I need this for *fast* graphics, and reloading a segment (selector) isn't
   very fast if i need to do this for every putpix!
2. Does realloc always return the same pointer if i try to shrink a previously
   allocated chunk of memory?

Thanx in advance
