what exactly do you want to do? Do you mean, which compiler version of KDE 
should you install, if you want to install RKWard using the "Custom 
installation"-procedure? It's MinGW4 32bit, then. I have made this explicit on 
our web instructions, now.

Same answer, if you are looking for the compiler to match the Windows binaries 
we provide (e.g. for custom-compilation of R add-on packages). It's MinGW4 
32bit.

Or do you want to compile RKWard from source? In this case either should be 
fine. For general information on this, see http://p.sf.net/rkward/windows 
(last section of the page).

We don't have the resources to compile a 64bit Windows version of RKWard, and 
thus compilation with MinGW4 64bit is untested. However, RKWard is built for 
other 64bit systems, regularly, and I don't expect any fundamental problems, 
here (if you run into anything, let us know on rkward-devel).

Note that the advantages of running a 64bit version of R are probably less 
pronounced than you may expect. See http://cran.r-
project.org/bin/windows/base/rw-FAQ.html , questions 2.27-2.29.

Thomas
