A change in profiles? 14.0/* adds that to the default CXXFLAGS in

make.conf, so users put it in place?
Before you invest any more time in this, please understand that C++98
and C++11 are source-incompatible. There is no way to expect that a
package builds fine when you throw -std=c++11 on it. And even if you
patched them all, you are breaking an unknown number of 3rd party
software over which you have exactly zero control.
Also note that as of gcc 4.8, the C++11 support is still labeled as
experimental and upstream developers announced they will introduce ABI
breaks in future.
With kind regards,
Jan
I would look to gcc-4.9 for C++11. By that point many upstream
providers will start to feel the pressure and patch for us.
