hello gsl guys,
maybe one should have a look into the matpack lib which is
a c++ library in order to fix the bugs below. as i could see
this lib is under GPL. ( http://www.matpack.de )
in the source code are references to the numerical algorithms
which are used.
The author may be contacted via: gammel@matpack.de

> BUG#1 -- gsl_sf_hyperg_2F1_e fails for some arguments
here one could have a look at the Laguerre Polynomials of matpack,
i guess that there is a connection to hyperg_2F1 function.
i haven't checked it
> BUG#3 -- gsl_sf_bessel_Jn fails for large argument
there is a Bessel function , first kind, order n, in matpack also
but this I haven't ckecked
> BUG#7 -- gsl_sf_coupling_3j loses accuracy for large arguments
3J-symbol in the matpack lib works perfectly is my impression even
for very large angular momenta
i have ckecked it out
