Awesome.

I should think of a really clever way to catch that before it happens.
Trouble here is that R doesn't 'read' the src/Makevars and simply lets make
and g++ (or clang++) take care of things so the failure is silent.

Yet extremely frustrating and tricky to debug.  If anybody has clever pointers...

PS The CXX_STD=CXX11 is mostly historic. R itself imposes that now ... as
will RcppArmadillo from the next release.
