@Cabin: Your build doesn't work under wine for me.
yeah, not working for me, either. Sounds like the one I'd want to try. Wish you guys were compiling on linux. I might have to break down and try my hand at trying to get some of your changes into the repo that's compiling on linux now. (that will take a long time I'm sure)
I've heard that.. unfortunately I don't know why my build would be different. I've seen two versions of mpir.dll floating around... maybe try the dll from mumus's build?
Rdebourbon also removed the problematic fastdiv test so his build will be similar to mine too. My only other speed change is noticing CPrimalityTestParams.fFermatTest is always false, and so you can follow the code and eliminate function params and if branches that are never used.
