Holy cow! It looks like I spoke too soon about all the reasonable people.
I think I've got the cygwin1.dll link working. I figure that Carlo has taken Operation Billion Digits to Level 2.2  three numbers to 68 digits then one to 69. It takes two more to 69 digits to reach Level 3 (3 numbers to 69 digits). I think I've captured all the advances at http://ElevenSmooth.com/Billion.html As Buzz Lightyear would say, To Infinity and Beyond! William

I will take one number to about 68bits maybe more. Here are the results so far:
M3321928307 no factor from 2^62 to 2^63. M3321928307 no factor from 2^63 to 2^65. I am running this on my Athalon 1100 (while P95 and the rest are going). If I run Linux, would I need the cygwin.dll's? Or won't that do it? I may try to refire my 200MMX into Linux.

Optimizations
Factor3_1.exe has been compiled with Athlon optimizations, while my linux box is a Pentium III Xeon.
Source code is available for Pentium 4 optimizations under GMP, provided that the one who compiles the source sends me a working binary of the file. You should have a GMP library installed and made on a Pentium 4 machine to try this. Maybe we can squeeze a few more seconds out of this program. Luigi

For me factor3_1 still isn't working. I got the two files, but it says the procedure entry point to cygwin1.dll isn't working.
