This looks like you're trying to compile with PostgreSQL cvs HEAD 
(8.2devel), correct? That won't work as I've not yet adjusted PL/R to 
handle NULL elements in arrays (which is brand new in HEAD). But this is 
is now off topic here...

Getting back on topic, unless someone can tell us that R.dll or some 
other mechanism exposes the same API as the libR shared object, I'd have 
to say it is probably hopeless.
