Instead of symlinking you can just install the gcc-3.3
This doesn't work on ubuntu64 as there are no 32bit gcc libs avalibale (there is for gcc-4.1+ (multilib package)). So basically you a screwed if you need to build/re-build modules. The only way is for BRL to update there code to link to gcc-4+, which I would suspect would break there code for windows as (mingw gcc-4+) is only a technology pre-view at the moment.
