Differences in Visual Studio vs OpenJDK compiles - jchar vs OLECHAR

I resolved this by disabling the Zc:wchar_t-  option in Visual Studio. 
>From the GUI I had set this via the file's property page:
  C++, Language settings, Treat wchar_t as Built-in Type, Yes
which is the default and which also matches the state of that option for
the OpenJDK build.  I had set that to fix some other problem but
fortunately no longer need it.
