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"`?
