GNUSSL is a C++ class-library, covering areas of linear algebra,
matrix decompositions and ffts in an object-oriented way. So it is
fairly different from GSL, where the goal is to write a portable
replacement in C for existing numerical libraries such as
IMSL/NAG/Numerical Recipes.

The projects began around the same time (roughly speaking) but are
independent.  I believe development of GNUSSL lapsed after a while.
I'm not sure why that was.
