 MS has come out with /permissive- (read more:

 This resulted in these errors:

 1>C:\Dev\Couloir\3pLibs\Boost\boost_1_64_0\boost/typeof/msvc/typeof_impl.hpp(125):
 error C2988: unrecognizable template declaration/definition (compiling

 I searched and found this:
 https://svn.boost.org/trac10/ticket/4593

 So, I defined _MSC_EXTENSIONS

 But I got the same errors.

 Any help would be greatly appreciated.
