Complex math functions closer to Hull, Fairgrieve and Tang


Hello all,
I would like to implement the GSL complex functions so that they
correspond more closely to those suggested by Hull, Fairgrieve and Tang,
"Implementing Complex Elementary Functions Using Exception Handling", ACM
Transactions on Mathematical Software, Volume 20 (1994), pp 215-244.

With regards to the function gsl_complex_abs, I am having a hard time
finding the implementation of hypot.  I understand that it is generally
platform dependent (depending on the installation); however, I am really
just interested (at least for now) in the implementation of gsl_hypot.  If
you could tell me which file in the gsl contains the implementation I
would appreciate it.

Thanks,
Andrew Binkley
