Comment (by johnmaddock):

 Update: I looked at this again with a view to making cautious use of
 __GLIBCXX__ when the compiler is clang, but __GLIBCXX__ versions are so
 scrambled up as to be functionally useless, for example looking at
 https://www.gnu.org/software/gcc/releases.html I see

 libstdc++ 4.3.5 later than 4.5
 libstdc++ 4.3.6 later than 4.6
 libstdc++ 4.5.4 later than 4.7
 libstdc++ 4.6.4 later than 4.8
 libstdc++ 4.7.4 later than 4.9

 And that's just the obvious ones, and doesn't include "unofficial"
 releases from Apple etc.

 Back to square 1...
