Doing this right now.

I will try. I am however not sure whether I can:
    a) follow every GMP release. Maybe my update frequency will be lower.
    b) port all functionality. I will appreciate any help here. Too 
early to determine now.
    c) make a thorough test of correctness of the modified GMP. Any 
suggestions on how to
        thoroughly check correctness of operations are appreciated.

It will be needed :-)
