gcc-3.4.1 under FC2 ?

[Horvath Andras]

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
