[GiNaC-devel] Bugfix for numerical integration.

Dear all, I discovered that the numerical integration routine that I wrote does not handle complex functions. The inequalities in the error checking are the problem. Therefore, I added some abs-function to the code. BTW, maybe it would be a good idea to include the numerical evalution for the gamma function that I comitted last friday in 1.3 as well? Maybe it could also go into release today? Bye, Chris
