: *May* not be a good comparison.  How about when both systems are
: running the same version of a cross compiler (GNU), compiling the
: same source code?

Nope. The GNU compiler is much more developed on some systems. For instance,
on intel x86 it is fairly developed... _but_ if you were to look into 
the Pentium GNU compiler (currently being developed), you would find that 
on Pentium & Pentium Pro machines it would compile up to 30% _faster_. 
I would strongly suspect the the GNU compiler is at different stages of
development on intel vs sparc systems, and know it is quite a bit behind
on Alpha systems.
