Hi,

Thanks for your email.  If you plan to distribute it, I'd ask for a
different prefix from "gsl_" to avoid confusion.  I put some notes
about making extensions at http://sourceware.org/gsl/design/gsl-design.html#SEC2 
If you want to follow those I can list it as an extension at
http://www.gnu.org/software/gsl/ if you like.
