[Rd] question about Makeconf and nvcc/CUDA

You will need a src/Makevars.win to get a .cu file to compile.  It is 
not a known extension: see §1.1.4 of 'Writing R Extensions'

Most likely you need something like

cudasize.dll:
	nvcc -m32 --shared -o $@ cuda4.cu

in Makevars.win.

Also, heed the advice about trying R CMD INSTALL before R CMD check.
