When I hit ths problem, someone recommended LAPACK, which 
I then used happily (routine DGEEV). This mailing list has
seen occasional discusions about how to wrap/merge/whatever
LAPACK routines with gsl (a technical problem is that LAPACK
uses the fortran calling convention, making it ugly in C.)

Is this right? isn't there a  "DOUBLE_RADIX" ?
