Changing GCC Default Version

[The X Reality]

I've installed GCC 4.0.3, and have switched the default. Is this all I need to do? The fact that `gcc --version' still outputs information about version 3.4.5 concerns me.

changing the default compiler in lunar only changes it for lunar compiles, and some modules might not even pick up the alternative compiler too and refrain from using e.g. gcc4.

This is intentional - it is uncertain how a mixed base system behaves when compiled with different compilers.

As user, you can add the PATH to the different compiler to set it the default for user compiles.
