I am a bit lost, since the small snippet below does not compile on MSVC

It compiles with this MSVC online compiler: http://webcompiler.cloudapp.net/
According to https://msdn.microsoft.com/en-us/library/hh567368.aspx#featurelist
it should also compile with MSVC 2013.
Earlier versions do not work because of TestDeleted.
Uwe, can you please apply the patch from Kornel in the first message in this
thread, delete CMakeCache.txt, try to build and then send me
CMakeFiles/CMakeError.log? It is too big for the list. This file will tell
us what goes wrong with the test.
Maybe also use '--debug-output' as an extra cmake parameter. Than also the file
CMakeFiles/CMakeOutput.log may be of interest.
I'd like to have both files too.
If it compiles (with any needed compiler flags), then the last patch I
sent (in the starting mail on this thread) should be similar.
Sources changed slightly in the meantime, so the patch may not apply
cleanly. My latest guess was the flag "/Ze" to enable MSVC extensions, but
I got no response ...
Sorry, I overlooked that. /Ze is for Microsoft extensions, this is not
needed.
OK.

Isn't this too much trouble? msvc2013 and msvc2015 have C++11 enabled by
default.
Not much to do in the cmake files, and whan something has to be changed just use
cmake variables MSVC2012/MSVC2014. Or have I missed something?
