Mostly. There are a couple of things that explicitly create problems for
m == 2003 and there is the problem of at least one semantic change that
can potentially result in miscompiled code (destructors are tagged as
not throwing by default in 2011). For m>=2011 it should be transparent.
There is also the ABI breaking mess in libstdc++ to consider of course,
i.e. depending on how libstdc++ from GCC 5.1+ is installed, code
compiled with -std=c++11 may or may not link correctly with -std=c++03.
