Thanks... Not sure; could be but maybe not. The reason is that
y = GAMMA(real(pop(&a)));
push(Gcomplex(&a, signgam * gp_exp(y), 0.0));
doesn't make any sense anymore if GAMMA is "true" gamma rather than log gamma. I guess it doesn't pay to understand what it is beyond the fact we know gamma() = tgamma() on your system.
I'd say this needs to be addressed before 4.2 release.
