[Distutils] Strict/Loose Version and toolchains checks

Hi, Since we are talking about versioning, here is one more complaint which may fall into the bugreport category or not, I am not sure. There are some version checks in some codepaths which do not make much sense IMHO, in particular: - distutils checks the versions of the toolchain. This is broken. If I want to use gcc built from svn to build my extensions, distutils should just do what I ask it to do, and not barf as it currently does. - bdist_msi also fails to run when the project version is not a released version. I can't see the rationale for that behavior, and it is not consistent with others bdist_ anyway. thanks, David
