If the only function of these files within the R package in question
is to be included into the other C++ files, then perhaps you could put
them in another directory and include them from there:

 #include "../extrasrc/foo.cpp"

 I'm not sure if the forward slash will work in non-Unix OSs, but it might...

 There may be some make-magic to tell make to exclude some files from
its implicit build rules, but I don't know what it is.
