--- Comment #23 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-06-14 16:22:05 UTC --- (In reply to comment #21) > So this boils down to that we cannot have a c++11/non-c++11 heterogenous > environment on a system. One would have to build all libraries for both > standards until c++11 is well established. See http://gcc.gnu.org/ml/gcc/2012-06/msg00201.html and http://gcc.gnu.org/wiki/Cxx11AbiCompatibility has some more details on incompatibilities. Bugzilla is the wrong place to discuss it, this PR is a dup of the std::pair issue.
