Does your version use the GMP library (optional in PARI). Does it support Windows? I couldn't tell if the PARI Windows distribution has GMP, but I suspect not since GMP doesn't support Windows. > Here I put some screenshots.

Am I gonna have to re-compile Python? That's imposible for ordinary Windows users. Are you going to make a binary Windows distribution?
