Hmm, do we really need to change this?

We have to take into account that people may have their own/custom implementations of classes that derive from Compiler, they will need to be adjusted accordingly (and we have no easy way to produce a clean error message there, I think)...

A deprecation warning has been implemented by @Micket in Compiler._set_compiler_flags, so this change won't cause any silent breakage.
