As AppVeyor CI ran on the beta tag, I'm also seeing Boost.Log failures 
caused by Boost.ASIO on:

* MinGW 32-bit, gcc 5.3
* MinGW-w64 32 and 64-bit, gcc 6.3

The error is the same:

In file included from libs\log\src\syslog_backend.cpp:31:0:

Note: The error happens regardless of C++ version, you can see it 
multiple times in the build logs.
