The link to the newer version is to file://something.  If that's the one
you'd like people to try, let us know when the link is fixed.

See http://gcc.gnu.org/gcc-3.0/lapack-guide.html for an example of
useful instructions for trying out your library.  Please explain how
to compile with a specified set of compilation options; building with
different sets of optimization flags is a good way to flush out
compiler bugs.

I'm pounding on the GCC 3.1 prerelease on ia64-linux and look forward to
trying out your library.
