BTW, I located more NR code in GRASS. The eigen and Jacobi routines use
them. I've also discovered that the NR routines are inherently
unstable, but that also applies to most OSS solutions.
Both Soren and myself would like to replace the BLAS/LAPACK (Fortran
code) libraries with ATLAS, a tuned C version. This also gets us away
from the Fortran issues suffered by gcc4.
If there are no objections, I would like to go ahead and modify
configure.in and include/ to reflect this. Soren has already created a
good wrapper API for the functionality and has expanded it extensively.
I didn't note any objections when I queried the devel list, but I think
this is sufficiently large enough to be voted on by the PSC.
I really can't complete my imagery/ and lib/gmath API changes until
ATLAS (or some equivalent..maybe even GSL?) has replaced existing
BLAS/LAPACK.

I've been adding them to all files I've touched...and I've touched quite
a few lately.

Agreed.
