VS 2010 with LLVM

[aaron.adato@…]

I can't compile anything that includes BOOST when I use as a compiler clang on MSVC 2010/2013. The error is a compiler error and not a linker error. I already built BOOST for CLANG on windows, but I didn't get to the linking stage.

Here is the error log:

sp_counted_base_clang.hpp is included when __has_extension( __c_atomic__ ), which should mean that the C11 keyword _Atomic is available. This does seem to be the case for Clang on other platforms. You might want to inquire about this in a clang-cl specific forum.
