Firstly, many thanks for this tip. I had no idea that Boost.Build 
could be told that a library requires certain C++ features. AFIO now 
uses that facility, and that let me clean out some cruft. Thank you.

I do wish to reiterate my desire for a std=98|03|11|14|1z parameter 
for ./b2. I think users get confused - as you can see on 
stackoverflow - on how to build Boost for C++ 11 or 14 or 1z. A 
simple

./b2 toolset=clang std=14

... I think is clear and obvious and memorable.

Niall
