32bit vs 64bit 

Hi,

factorint(N,6) performs better when using 32bit binary than when using
64bit binary - about 30% better on <70-digit numbers .  The test was
done on a multi-CPU Opteron machine.  Considering that 64 bit about
40% faster than 32 bit on PARI testbench, I find this MPQS discrepancy
peculiar.  

Thanks

Igor
