Another issue in this matter is credibility. When Octave uses these
classics, like QUADPACK and so on, we know that they work. Or at least
we have a big confidence in them because they are on Netlib, because 
everybody uses them, etc. If you start translating (and thus changing) 
the orginal code, confidence drops to a low level. At least in my case :-)
