Hi Michael,

I just installed Visual Studio 2017 and tested with that, using the default settings.  It fails with the same error as 2015

h:\epics-devel\base-7.0.1\modules\pva2pva\pdbapp\pdbgroup.h(197): warning C4996: 'std::tr1': warning STL4002: The non-Standard std::tr1 namespace and TR1-only machinery are deprecated and will be REMOVED.

I then added the flags 
/std:c++14 
-D_SILENCE_TR1_NAMESPACE_DEPRECATION_WARNING

But it still fails with the same error.

Is it worth trying /std:c++17 or /std:c++latest?

It seems like the APS Jenkins Build server should be upgraded to VS2017 Community so these problems can be caught earlier in the development cycle.
