It is not accurate to blaim M$ for this. Supported (by M$) operating
systems are W7SP1, W8.1 and W10 (and their server counterparts) and no
others. They all come with their own compiler, and are therefore the the
compilers [VS2010-VS2015] that need support (in PP or otherwise) and no
more. These compilers all have C++11 support, to some extent, but
progressively more of it.

You are perfectly correct on this one. This should apply to boost as well,
and would probably make Edward's life a lot easier. Plenty of stuff
concerning VC7 (*Visual C++ .NET 2002, 32-bit only*) and VC8 (*Visual C++
2005*) in the code-base of boost (typeof/type_traits)...

I always say, follow the money, M$ might have a hand in this.
