Hi, I am working on developing scientific flow simulation codes in C (number crunching). I would like to try whether gcc-3.4.1 generates significantly better code than gcc-3.3.3 in FC2. (In release notes of gcc-3.4.1 a lot of improvement in optimization is issued.) How can I install gcc-3.4.1 on FC2 so that original gcc remain untouched? (As I know, replacing gcc with a newer version can arise problems. Or is it false?) I want to use gcc-3.4.1 for compiling my own C codes only. Thank you in advance, András
