It was even more wrong in R-devel, for there we have sub-architectures and 
it needs to be "-I${R_INCLUDE_DIR} -I${R_INCLUDE_DIR}${R_ARCH}".
Fixed now, thanks.

I don't think there is any problem in R.sh.in.

Well, only 5 CRAN packages have a src/Makefile, and one other has 
src/Makefile.in.  Of those only ROracle appears to have $R_HOME/include.
So I'm missing something.

When 2.3.0 is nearer release this will need to go into the update notes.

It should just need the right environment variables.
