> What are the differences between these compilers; is there or will There's only two major gcc versions other than gcc itself - egcs and pgcc. egcs is intended to do exactly the same job as gcc, it just uses a more open developement model. As a result, it contains a large number of improvements over plain gcc. It also rolls in the Fortran front end (the FSF one is distributed seperately from gcc), and when version 1.2 is released it will also have front ends for Chill and Java. pgcc is targeted at the Pentium. It's much less stable on other processors (last time I tried it wouldn't even build on anything except i386) but on ix86 chips it should produce faster code. The improvements vary, but typical figures seem to be about 5-10%. Improvements are gradually being folded into egcs, but often things need reimplementing in a more general fashion and there are problems with the licensing of some of the code which mean it can't go into FSF gcc or egcs. There is another compiler called pgcc out there, the commercial Portland Group C compiler, but that's nothing to do with gcc. > there be a pgcc Deb package? Perhaps. If someone packages it, I guess. You could ask the Debian egcs maintainers. The main technical argument against it would be stability. -- Mark Brown mailto:[EMAIL PROTECTED] (Trying to avoid grumpiness) http://www.tardis.ed.ac.uk/~broonie/ EUFS http://www.eusa.ed.ac.uk/societies/filmsoc/
