Hmm, Glynn said that gcc doesn't save any general purpose registers
except EBP. This definitely means EAX/EBX/ECX/EDX/ESI/EDI, I think.
(Or that is what I understood.)

Well, right now it's _only_ for testing purposes. It might be good
idea to release an optimized version for general use, however...
- I would download the latest version of bzip2 for this. 
- I want people to try out if it's faster on other people's
  computer and not just in mine. Any volunteers? :)
(being only for testing purposes here means only for x86 8-)
