 Summary:

 The first version to have something interesting (lambda expressions, rvalue 
references, static_assert) is MSVC2010. Range-based for loop is MSVC2012, 
which has only RC out by now, and requires Window7+. Some stuff, such as 
variadic templates or delegating ctors, are not there at all.

 So, as long as we require to build LO with MSVC, we can revisit the question 
of hard-depending on C++11 in, uhm, let's be optimistic and say 3 years. IOW, 
we can probably get there faster by ditching backwards ABI compatibility with 
LO4 and switching to a different compiler for Windows.
