The only When reading the name pcc my first thought was: isn't that the compiler that was distributed on later Unix V7 tapes? And yes, the web-page says it is based on that one. I'm quite sure that the original code had no BSD copyright, so I wonder how it obtained one? For the rewritten code there is no question, but what for the remaining original code? Has it been relicensed by the original author? It's interesting that the compiler is so much faster than gcc. I remember that it was around 3-5 times slower than the dmr compiler under V7. This tells a lot about gcc's speed :-( harti
