Compiler Version warnings

[SuperHackio]

It was found on stream that only CodeWarrior Wii 1.3 works properly with certain Syati headers. Is this OK? Should we make other versions work as well? At the very least we should have the version used by Nintendo for SMG2

There are macros that exposes the compiler version, but in reality it's better off just using a single version as it reduces clutter and keeps bugs consistent to that specific version as CW versions have their own bugs.
