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.
