That's what I said. g++-6 and up (and clang++-6.0 and up) are C++14 by 
default.

As far as I can see, the major problem with b2 dropping C++03 was not the 
fact that it happened, but that it happened without Boost announcing that 
C++03 is no longer supported for building Boost.

Technically, you could still build Boost if you compiled just b2 
with -std=c++11, but in the real world nobody cares for that distinction. 
Boost doesn't build, and that's that.
