The runtime library is the key point here (not the language version).  The use of libc++ (or a newer libstdc++) enables support for C++11 features in the relevant compilers.

Aha. That's the bit I hadn't grokked. I had /thought/ that the
following case would /not/ work:

Project A built with std=c++11, Project B built with std=c++03, … A
links to B … A passes a string (or some other STL type) constructed in
“C++11-world” to B, which then works on it in “C++03-world”.

This thread, and further reading, suggests that this /will/ work fine,
provided the runtime linked by both A and B supports C++11 … :)
