I notice than in the write-up for bug #45746 it is suggested that multiprecision
arithmetic be used in a portion of the calculation to produce a more precise
result. Is this something that would be considered in GSL? I did a search
through the code for mpfr or gmp and did not find either. In fact I couldn't find
any code where multiprecision arithmetic is currently being used. Is it GSL
policy to keep all internal calculations in double precision?

Yes for now I think it would add too much complexity to GSL, so we 
prefer to use double precision.

Thanks for your work on the recent bugs - I haven't had a chance to look 
at the patches but I'm hoping to get to this soon.
