It may not be true any more. A friend of mine brought a little fortran
program (It is two big do loops with some instrinsic function calculation in
the loop.) and the C translation of the fortran program. We compiled two
program on a IBM RISC System 6000/530 with xlc and xlf. To my surprise, the
excutable from C is faster than the excutable from Fortran by a few percent.
