Yes, the 'methods' package implements much of the changes in S version 4, and there are quite a few nods to S4 elsewhere in the code. That is mentioned in the on-line errata files.

You seem to be assuming Windows. The recommended compiler (MinGW gcc) and toolset work best. If you write C++, you need to use a C++ compiler, but remember that C++ is not binary compatible across compilers (or even compiler versions) and also that you need to use C bindings. If you don't need C++ features, use a C compiler.
