Hi Chase,

Matthias just pointed me to 
http://gcc.gnu.org/wiki/Cxx11AbiCompatibility on IRC, so it seems that 
this behaviour is expected.

So, either we need to build some libraries more than once or we need to 
enforce the language standard for all modules in the archive that expose 
STL in public API's (or consume these public API's).
