Hmm, that's alarming. Any clang or user-config.jam experts out there who
can tell me what switches are needed to get C++11/14/1x/1y/1z/etc support
to turn on?


I believe you need to add <cxxflags> or <compileflags> plus quotes to
user-config.jam.

Example:
using clang : 3.5~c++14 : clang++-3.5 : <cxxflags>"-Wno-c99-extensions
-std=c++14" ;


Thanks! I'll go start rebuilding the docker images with an updated
user-config.jam.

Do you know where this is documented so I can reference it?

 It's mostly documented here:
http://www.boost.org/build/doc/html/bbv2/reference/tools.html

Yeah, that looks familiar. Despite what I had pasted previously, my user-config.jam did have the <cxxflags> section, but the problem was that I wasn't quoting the options that followed, so the second one (-std=c++14) was getting cut off. 

If I get time, I'll submit a pull request against that page to add an actual example showing how to group multiple options that way.

Out of curosity/clarity, is it possible to specify multiple instances of a tag instead of quoting? e.g. `<cxxflags>-Wno-c99-extensions <cxxflags>-std=c++14` instead of `<cxxflags>"-Wno-c99-extensions -std=c++14"`?
