There is a 4.6.2-1 in the link above, but no 4.6.4. That's why I was
wondering why you are specifying 4.6.4.

Did you find any tests not working in ASIO and Thread when using gcc
4.7+ on up with MingW ? Or was it just in your own work with AFIO ?

I will read about it. You are implying that the MingW-w64 people were
not happy with the quality of MingW. I will look for information about this.

It sounds like you able to test clang under Windows using the MingW-w64
RTL and the Boost Build clang toolset.

Got it. Thanks !
