GMP on Pentium 2

[delta trinity]

Humm, probably yes.

Maybe something have been optimized in Athlon asm files and not done in P2 
asm files.  Like if when compiling for P2, a generic Pentium 1 file is used 
and when compiling for Athlin, it's using athlon-specific files.  Well, I 
can only guess... :)
