R 3.1.0 and C++11

| 
| Following up on the thread spawned a while back, I just wanted to say that I
| appreciate today's RSS serving of R-devel NEWS:
| 
|    CHANGES IN R-devel PACKAGE INSTALLATION
| 
|    There is _experimental_ support for compiling C++11 code in packages. The
|    file ?src/Makevars? or ?src/Makevars.win? should define the macro
|    ?USE_CXX11 = true?. Where needed, an alternative C++11 compiler can be
|    specified by setting macros ?CXX11?, ?CXX11FLAGS? and so on, either when R
|    is configured or in a personal ?Makevars? file. (The default is to use
|    ?$(CXX) -std=c++11?.) 
| 
| Thanks for initial and incremental changes. They are appreciated.

And now a big thanks to Martyn and anybody else in R Core who pushed this
through to the R 3.1.0 release this morning.

Having Makevars to let us say CXX_STD = CXX11 (plus the other variants) is a
real step forward, and relying on the information gleaned at configuration
time for R is sensible too.   

It's really good to have this, so thanks again.
