>Description:

when using ``factor'' on the alpha platform it gives a wrong result
when someone tries to factor numbers > 4294967295 that contain of 
factors that are >= 65539.

$ factor $(echo "65539*65539" | bc -q)
4295360521: 4295360521
            ^^^^^^^^^^ wrong.

>How-To-Repeat:

$ factor 4295360521

>Fix:

i think its not easy to fix without modifying /usr/src/games/primes/pr_tbl.c
