Experimental Support for Windows
--------------------------------
The Windows support requires building with clang-cl as cl does not support one
required extension: `#include_next`. Furthermore, VS 2015 or newer (19.00) is
required. In the case of clang-cl, we need to specify the "MS Compatibility
Version" as it defaults to 2014 (18.00).

~~~~~~~~~~~~~~~~~~~~~
Building with Visual Studio currently does not permit running tests. However,
it is the simplest way to build.

Building with ninja is required for development to enable tests.
Unfortunately, doing so requires additional configuration as we cannot
just specify a toolset.

directory separator as clang-cl may otherwise parse the path as an argument.

**_LIBCPP_METHOD_TEMPLATE_IMPLICIT_INSTANTIATION_VIS**
Mark a symbol as hidden so it will not be exported from shared libraries. This
is intended specifically for method templates of either classes marked with
`_LIBCPP_TYPE_VIS` or classes with an extern template instantiation
declaration marked with `_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS`.
When building libc++ with hidden visibility, we want explicit template
instantiations to export members, which is consistent with existing Windows
behavior. We also want classes annotated with `_LIBCPP_TYPE_VIS` to export
their members, which is again consistent with existing Windows behavior.
Both these changes are necessary for clients to be able to link against a
libc++ DSO built with hidden visibility without encountering missing symbols.
An unfortunate side effect, however, is that method templates of classes
either marked `_LIBCPP_TYPE_VIS` or with extern template instantiation
declarations marked with `_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS` also get default
visibility when instantiated. These methods are often implicitly instantiated
inside other libraries which use the libc++ headers, and will therefore end up
being exported from those libraries, since those implicit instantiations will
receive default visibility. This is not acceptable for libraries that wish to
control their visibility, and led to PR30642.
Consequently, all such problematic method templates are explicitly marked
either hidden (via this macro) or inline, so that they don't leak into client
libraries. The problematic methods were found by running
`bad-visibility-finder <https://github.com/smeenai/bad-visibility-finder>`_
against the libc++ headers after making `_LIBCPP_TYPE_VIS` and
`_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS` expand to default visibility.

* r296729 - Remove std::num_get template methods which should be inline
These functions should never have had visible definitions in the dylib but
since they were previously not specified with 'inline' they accidentally
got emitted. This change is non-ABI breaking because every "linkage unit"
must contain its own definition.
