Sorry, I don't have a 64-bit processor... I'm working on somehow old
hardware, usually.
Anyway I think there is also another problem in my measure, I did not
"tune".
I was trying an update of the compiler to gcc-4.4...
Then I'll recompile the three libraries, retune them, recompile again,
and test.
If you are interested, I'll send the new result here again.
