Query: Are you talking about just the C interface to LAPACK or the C
interface to the BLAS, too? I definitely want to keep the BLAS C
interface. It would be nice if there were a C interface to the entire
LAPACK, but I don't think that ATLAS (or anyone else) provides that
currently. That way, we would be able to worry less about mixing and
matching Fortran compilers (e.g. your distro builds ATLAS's LAPACK
with g77 and you want to use gfortran to build scipy). But since
ATLAS's LAPACK is a mixture of C and FORTRAN, I think we may be pretty
much stuck with that problem regardless.
