In the current R for Windows it is possible to build a dll that calls
routines in the main executable. You need to build the dll with Watcom
Version 10 (not 11; 11 seems to have a horrendous number of bugs in the
dll compiler). Watcom is the only development environment that seems to
allow unspecified references in the dll that will be resolved at run-time.

In the very near future a new version of R for Windows (different from
Guido's) should be available with more of the R internals explicitly exported.
There seems to be no way to export all of them and there seems to be an
overhead in exporting functions so we probably only will export a selection
of them. Those needed for the libraries that we currently have will be included.

There are lots of changes to the c functions in R/src/windows made over
the last few days. These bring the graphics in to line and provide a 
fairly different user interface. I'm hoping to have RMay out.....
