FWIW, I think it is fine to require C++11 if there are sufficient
benefits we can derive from it. This seems like a good example
of something we could simplify greatly if we did?

Note that I wouldn't necessarily think in purely in terms of which
version of GCC supports it, but also consider whether want to support
building GDB with non-GCC compilers, particularly on the more exotic
systems out there, where it can be hard to build GDB. Do all these
compilers support C++11? Probably not.  This is where it becomes
a judgment call for me.  Making it easy to build with other compilers
by limiting which parts of the language we can use helps getting wider
use of GDB; but on the other hand, if it comes at too much of a cost
in terms of the code and its maintenance, then it seems better overall
to increase our list of requirements.
