Combining -fexternal-blas and -fdefault-real-8 would add needless complexity to the compiler. The correct solution is to write proper Fortran code. To be even more specific, don't use -fdefault-real-8. It was a really, really, bad idea and was only supplied to give backwards compatibility with g77.
