Visual Studio 2017 build errors with 1.41 platform toolset

Hi all,

Trying to build a bare-bones project in VS2017 including <sol/sol.hpp> and using 1.41 platform toolset produces a bunch of errors:

Toggling Conformance mode does nothing.
The same project builds fine under VS2019 using 1.42 platform toolset.

Is there any way I can get it to build under VS2017 with the 1.41 toolset?

EDIT: As usual, a last-second check after posting something... Including the single header seems to build just fine.

Well, I'm glad it's okay. If things break again, let me know.
