Warn if g++ < 4.8, C++ standard library is too old

Not ready for merging. Want the Clang 3.6 patchset to land first:

A whole bunch more of the C++11 checks can be removed, we can unconditionally use -std=c++11,
among other things with this change. I'm trying to keep the patch relatively minimal though
unless we hit a problem after application and have to roll it back.

Explicitly don't check clang version number, since extracting it is hard (OS X clang behaves
differently than Linux clang), and 'clang -dumpversion' always reports 4.2.1 for compatibility
with some random tools...

Diffs (updated)

Basic hand testing gcc 4.9.2, gcc 4.4.7, clang 3.6 all on Windows
