Yes. This will change for R 2.3.0 (see the nightly builds).

Not necessarily. If OpeNDAP libraries use ABIs that don't differ  
between 3.3. and 4.0 then it should work. Note that you still have to  
compile the R package with gcc 3.x, however the library it is linking  
to doesn't always have to be compiled with gcc 3.x.
