Oh well. Thanks for checking into that. Still, it seems odd. It must make life hard for C coders who link to these libs. I would have thought that (compatible ordering) would be a big reason for rewriting in C.

Yes. I noticed that some time back. (OS X, right?) But I think these libs contain both Fortran and C versions.
