Did you mean to say 'defines _MSC_VER to 1310' ? If a compiler defines
_MSC_VER to 1300, that is MSVC 7.0 compatibility, so not supporting a
7.1 feature is not unexpected.

However, if the compiler says it is 7.1 compatible (1310), why is it
unlikely to support ReadWriteBarrier (a 7.1 feature, so part of 7.1
compatibility)?

Thanks,

Steve.
