That's not what I wrote in comment #16, and see Jason's
reply in comment #24.
I have no problem with g++ growing feature towards full
support of c++11.
I have no problems with libstdc++v3 using the limited set
of c++11 that are already available.
I do, however, have a problem with g++ defining
__cplusplus == 201103L in violation of ISO/IEC 14882:2011
Secs. 1.4 and 16.8 (note I only have n3242.pdf, so the
section numbers may be wrong in comparison to the ratified
standard).
If you want to help and want to keep __cplusplus == 201103L,
please supply appropriate recipes for fixincludes to catch all
of the currently unimplemented c++11 features, which g++
currently claims to support.
