Status update on this issue:

The problem has been fixed in develop in commit:

https://github.com/boostorg/asio/commit/cb75e92f14b3fd48b2baf54031d824e75c09a324

It has not been merged to master yet, so Boost.Log in master still fails 
to build with the above errors.

PS: I reported the problem in this issue:
