glog on visual studio 2015

I am trying to build Google glog library on windows using Visual Studio 2015. After adding #include to get around the std::min problem on Windows, I get to 2 main errors (1 repeats a few times) below. 

1>c:\glog\glog-0.3.3\src\windows\port.h(117): warning C4005: 'va_copy': macro redefinition
1>  c:\program files (x86)\microsoft visual studio 14.0\vc\include\stdarg.h(20): note: see previous definition of 'va_copy'

Seems to be an issue with the compiler generated move function, but explicitly deleting it does not work either.

LogMessage(const LogMessage&&) = delete;

Any ideas?

Cheers, Mike

The generated function is not LogMessage(const LogMessage&&) = delete;
but it is:
LogStream::LogStream(google::LogMessage::LogStream &&).

Internaly it will try to call the copy constructor of LogStream and hence the ostream which is marked as deleted.
Solution:
declare inside LogStream class:
LogStream(const LogStream&) = delete;
LogStream& operator=(const LogStream&) = delete;;
