That's great that it builds now. Well done, and thanks for the effort!! Our XGCD has changed, but I don't think we define a normalisation as such. From the manual:
"Set g to the greatest common divisor of a and b, and in addition set s and t to coefficients satisfying as + bt = g. g is always positive, even if one or both of a and b are negative." GMP recently changed back to their old normalisation. It looks, from the test results below that we screw up Pari anyway, so we have to change something, it seems. Given that GMP changed back to the old normalisation to support Pari, we should probably do the same. I'm afraid this is not an issue we can resolve easily. The XGCD code is very complex and it will take quite some time to rewrite it to handle normalisation (which it currently just doesn't do at all). Bill.
