More numbers!

------ 64 bits CPU -------
original:  885.0 ms
fast long: 746.8 ms (+16%) -- issue #3944 
--------------------------

+16% only with an optimized multiplicaton, great job Pernici :-)

------ 32 bits CPU -------
original: 1564.3 ms
30 bits: 1497.3 ms (+4%)
fast long: 1591.7 ms (-2%)
GMP: 1564.4 ms (=)
--------------------------

It looks like the operation 32 bits x 32 bits is slower on a 32 bits 
CPU, the gain is small (only +4%). fast long and a little bit slower, 
and GMP patch doesn't change anything.
