Hello, I need gcc 4.3 to compile a specific application. I am hoping that I can install gcc 4.3 alongside 4.1.1 without suffering some awful catastrophe. This is the output of emerge on the machine in question:
emerge -pv gcc These are the packages that would be merged, in order: Calculating dependencies... done!

Thanks, Roger
