> > -Adds a __config_site file that contains some libc++ macros.
> > -Links libcpmt.lib/msvcprt.lib (C++ std library headers on windows) to
> > the link, which provide exception_ptr definitions. Previously,
> > a file was including a windows header that would link these
> > headers, but that header is no longer being included.
