Isn't Diego just starting a gcc-4.9 tinderbox run?

It might be worth to try with -std=gnu++11 immediately:
Most API incompatibilities which I experienced in my projects
were either name clashes (with symbols not existing yet in c++98)
or other trivial things (like some "char *" returns intead of
"const char *" returns etc.); cleanly written code is likely
to be upward compatible without any issues.
