Re: [boost] PSA: Travis OS X bottleneck, <cxxstd> new Boost.Build feature

On a not entirely unrelated note, Rene Rivera has added a new feature <cxxstd> to Boost.Build that controls the C++ standard in use. So for instance, instead of the old

   b2 libs/mylib/test toolset=gcc cxxflags=-std=c++11

one can now use

   b2 libs/mylib/test toolset=gcc cxxstd=11

Sounds great. Does it always expand to c++XX or is there a way to specify gnu++XX?
