Which are only used on Windows, so presumably you forgot to mention that OS.

CRAN will neither accept packages with binary code files, nor will it 
accept packages tied to one architecture and OS (as such files would 
be).  You can do what you like provided you do not want to distribute 
the package: at that point you need to meet the conditions of the 
license and of the repository.

There are several examples of CRAN packages which compile up 
executables: arulesSequences is one.  But note that this is tricky as 
platforms such as Windows and OS X support multiple architectures in the 
same package installation.

And that does make clear that this is (or would rapidly become) a 
R-devel topic.
