Lambdas really do clean things up nicely in some places. It pains me to have to write function objects at work knowing this.

That must be annoying. Why can't you switch to C++11/14?

Reliance on certain, newly-deprecated things like gnu hash_map which has performance characteristics important to our specific application.

[lholden]

Does -std=gnu++11? not still support the gnu version?

You can use hash_map just find in C++11/14 mode, you'll just a nag #warning at compile time.
