OK, coming soon...

That's fine, you can simply replace the f2c-generated code by
Fortran-compiled code, as long as the calling conventions are the
same. I have used optimized BLAS as well on some machines.

Sure, f2c generates the underscores. But the LAPACK interface code
(the one I'll send you, and also LAPACK Lite) supports both
conventions, controlled by the preprocessor symbol NO_APPEND_FORTRAN
(maybe not the most obvious name). On the other hand, there is
no support for uppercase names; that convention is not used in the
Unix world. But I suppose it could be added by machine transformation
of the code.
