[Help-gsl] Announcement and Question - jacobi

Hello, I just released an extension to gsl that computes jacobi polynomials, 
zeros of jacobi polynomials and several operations related to Gauss-Jacobi 
quadrature (numerical integration,  numerical derivatives and interpolation 
using the quadrature nodes).

The extension can be found at:

Now comes the question:

I still have not implemented the error estimates. I tried to look at the code 
used to compute Legendre polynomials but I couldn't figure where did the error 
come from. Apparently it is related to the number of floating point operations. 
Does any one have any hints or references on that that I could use?

Thanks for any help.
