In which case it does no harm.
To clarify: same compiler can support different versions of C++ standard. Those versions are not guaranteed to be compatible, and e.g. chromium fails to compile when -std=gnu++11 is forced (<https://bugs.gentoo.org/show_bug.cgi?id=439698>), while is otherwise compatible with gcc-4.7.
