Well, since g++-4.9 now c++11 feature complete (with one exception
afair) the situation is probably a lot better now.
I maintain one packages (mia) that requires c++11 and it c++11 features
since they were introduced in g++ 4.5 (I am also upstream). I happily
link in various C++ libraries that are compiled without C++11 enabled,
and software that depends on mia also links with other C++ libraries
like gtkmm without problems.
The only problem I came across in all this time was with BOOST, it
exposed some enums differently depending on the use of c++11, i.e. they
used the new enum class with c++11, but when the libraries were compiled
without c++11, then interface provided by the headers did not correspond
to the compiled code (They actually could have actually avoided this
incompatibility, and I don't know if they do so now).
hope that helps,
