Michael,
You are getting confused in compiler minutia when you could be concentrating
on your code. The inline package can help here.
Consider the snippet below which loads inline, defines your function body
sans headers etc and then uses the magic of inline to compile, link and load
your fun

Surely you saw in the posting guide that R-help is not the place for
questions about C, C++, Fortran code? Diverting to R-devel.
