This is caused by following line in files: and.hpp, bitand.hpp, or.hpp, bitor.hpp:

#if defined(_MSC_VER) && !defined(__clang__)

This is not true anymore today. Commenting out the second conditions helps. Pure clang defines _MSC_VER plus __clang__ on windows.

This need to be solved urgently

@Milerius MPL has no dedicated maintainer and the issue is not a regression, you best bet is to develop a fix and file it via pull request

This is for clang on Windows targeting vc++. I have clang on Windows targeting vc++ and am able to test this using a the clang-win.jam file, but I need a simple example to test this issue. If just run the mpl tests with clang-win and the latest clang-10.0 on Windows targeting vc++ I see no failures in the tests. Please give a command line and some code where this bug is manifest. Whatever is the code you give in your initial post above I have no idea what is being compiled and what trhe clang command line is.

Seems this was fixed with newer boost. The fix is in this commit https://github.com/matbech/mpl/commit/d5fc194ce164301250f6feea9f194ccffdafb4f0
