I meet some 'Errors' When I compiled 'BLAS' in 'CLAPACK' or 'LAPACK' with gcc-
4.0.1. I think it is problem of accuracy of floating point calculation. With
or without gfortran I can find errors in BLAS test routine resulte.(XXXX.sum)
I use alton meachine with Redhat 9.0 Linux. gcc-2.95.3 gcc-2.96 gcc-3.2 gcc-
3.3.6 gcc-3.4.4 ....
