VS2015 : fatal error C1189: #error : <atomic> is not supported when compiling with /clr or /clr:pure

[Dima Rusyy <dima.ru.com@…>]

The code in boost/smart_ptr/detail/sp_counted_base.hpp :

#elif !defined( BOOST_NO_CXX11_HDR_ATOMIC )
# include <boost/smart_ptr/detail/sp_counted_base_std_atomic.hpp>

doesn't look correct as it causes <atomic> header to be included. That leads to compilation error in /clr mode.

Thanks for the report. I could work around that on the SmartPtr side, but it looks more like a Config problem.

Fixed in ​https://github.com/boostorg/config/commit/ab0fa3b3d72d67c4589bca554525057189cf08ae.

Note that I had to disable a heck of a lot of stuff... not sure how much of Boost is still working in that mode.
