[lldb-dev] MSVC 2013 w/ Python 2.7 is moving to an unsupported toolchain

[Zachary Turner via lldb-dev]

It's Server 2008 R2 technically, which is the server version of Win 7 (same
API set, same OS features, etc).  So yea, I'm pretty confident that test
coverage is going to be 100% the same across both.  It's just a matter of
if you want to have something that you maintain / have control over, or if
you want to test something in a different way than what we're testing.
