What's the concrete advantage of defaulting to Vista? Performance?
Yes, mostly. Vista has builtin support for condition variables and read/write mutexes, for example. Compiler-based TLS can be used safely with dlls. GetTickCount64 can also be useful in some contexts and is difficult to emulate. All these features will find their use at least in Boost.Sync and Boost.Log (the latter currently uses its own protocol for enabling use of these APIs, but it will be ported eventually).
If a program targets >= Vista, aren't defines available you could check anyway? Then there'd be no need to raise the default to Vista or to introduce a Boost WINAPI define. Olaf
