In yesterday's ESC we decided to on master drop MSVC 2012 in favor of 
2013 but keep GCC 4.6 for now.  (Which means that the features in the 
upper list will presumably become available on master while those in the 
lower list presumably won't.  I write "presumably" because the theory of 
the compilers' feature advertisements still has to pass the test of 
real-life usage in that notorious toolchain killer called LO.  Try 
things out with caution first.)

Maintainers of active Windows tinderboxes (on cc, as of 
<https://wiki.documentfoundation.org/Development/Tinderbox#List_of_registered_Tinderboxes>), 
please make sure until, say, mid of next week (Dec 3) that they are 
using MSVC 2013 for master builds.  I'll then make configure fail on 
anything less.
