In preparation for the upcoming release, I tried running the windows
builders. I'm seeing lots of issues with msvc-10.0, -11.0, and -12.0.

I know there has been some traffic about pushing forward changes that break
compatibility with older compilers...I'm guessing this is what is
happening, but wanted to double check.

1.  Are these errors due to removing compatibility in some library(ies)?
2.  Is the expected result of this compiler errors (vs. libraries that just
refuse to build)?

With the assumption that these are fine, I'm preparing to drop those three
versions from the build for this release.

Some examples...this one in msvc-10.0 seems like 10.0 just doesn't have
enough of C++11 (it has a lot, but not all).
compile-c-c++
D:\RB\bin.v2\boost\bin.v2\libs\chrono\build\msvc-10.0\debug\address-model-32\threading-multi\thread_clock.obj
thread_clock.cpp
D:\RB\boost_1_84_0\boost/chrono/detail/requires_cxx11.hpp(19): note: C++03
support was deprecated in Boost.Chrono 1.82 and was removed in Boost.Chrono
1.84.
D:\RB\boost_1_84_0\boost/ratio/ratio_fwd.hpp(35) : fatal error C1083:
Cannot open include file: 'ratio': No such file or directory

A lot of C++ 11 got added in 11.0/12.0, but apparently not all:
compile-c-c++
D:\RB\bin.v2\boost\bin.v2\libs\log\build\msvc-12.0\debug\address-model-32\threadapi-win32\threading-multi\attribute_value_set.obj
attribute_value_set.cpp
D:\RB\boost_1_84_0\boost/type_index/type_index_facade.hpp(59) : error

        D:\RB\boost_1_84_0\boost/type_index/type_index_facade.hpp(144) :

D:\RB\boost_1_84_0\boost/type_index/type_index_facade.hpp(68) : error

Full logs can be found here at this link. The files are big, scroll
approximately 1/3 of the way for each of 10.0, 11.0, 12.0 with 14.x being
the last couple pages.

Any thoughts?
