Maxima -- GPL CAS based on DOE-MACSYMA
Fixed in commit [71a379] merging branch bug-5743-bfloat-erf-erfc-slow Basically stopped using gamma_incomplete for bigfloats because that's slow. Instead use the power series or asymptotic series to compute erf/erfc. Use increased precision for these calculations.

Do the erf/erfc reflection inside the extra precision

elliptic_eu(u,m) is wrong when u lies in an odd 2*K period
