Good. That fixes my little snafu and gives me a moment to address it.  Maybe
I'll also add the -DWIN32 just to be safe.

That is precisely it.  

R-on-Windows still defaults to g++ 4.6.* which is older and less featureful.
R knows that, see how you now get  -std=c++0x   from setting the C++11 flag.

And it looks like the Armadillo code wants a newer compiler when C++11 is in
use, which would be a roadblock for you for the time being.  I can discuss
with Conrad whether it is worth covering this aspect at the Armadillo side,
but for now you are between a rock and hard place.

I would recommend looking through the files which come up below, and see if
you can identify additional #ifdef statements.  Armadillo is extremely well
structured and you may find another toggle to suppress the inclusion of
features which tickle the errors below, but which you do not need.  In that
additional -D... definitions may help you.

Keep us posted,  Dirk
