Thanks for your report! I can reproduce the this issue but it does not prevent the build to complete here. See for example: http://pari.math.u-bordeaux.fr/buildlogs/95a98c6f-3195-4782-bafe-ea8d4147f2da I do not know whether we want to actually use exp2 and log2 in this case, we might reopen the problem solved by 2.2.8-F43: 2.2.8-F43- Configure was missing log2/exp2 on systems that had it Cheers, Bill.
