[Rcpp-devel] C++11 in Windows R package

[Matteo Fasiolo]

Hi Dirk,

 after realizing that the only C++11 feature I was using was <random> I
decided to switch
to boost::normal_distribution. In particular I now link to BH, but I don't
use the boost::normal_distribution
from there, but the one in this commit:

http://lists.boost.org/boost-commit/2012/10/43158.php

which is much faster than the current version. Hopefully the package will
now work on all platforms!

Thanks,

Matteo
