See http://gcc.gnu.org/gcc-4.7/cxx0x_status.html for core language
status and http://gcc.gnu.org/onlinedocs/gcc-4.7.2/libstdc++/manual/manual/status.html#status.iso.2011
for library status.

GCC 4.7 is missing a few features such as inheriting constructors,
delegating constructors

GCC 4.7 has almost full support for the atomic and thread features.
