Xutility compile error for plugin


Noob question - I have not programmed in C/C++ for along time, so pretty rusty...

I got the host to compile, but I can't get a VST3 plugin (either my first jucer setup attempt or the juce example to compile)...

I have VS2013 community edition (also tried with VS2015 CE), and latest 3.6.5 SDK, (and previous 3.6.0) and found a copy of VST 2.4 on the web... installed in 



1>------ Build started: Project: SE1x, Configuration: Debug Win32 ------

    _RanIt base() const
        {    // return wrapped iterator
        return (current);


juce_VST3Headers.h, 57

#define base C:/SDKs/VST3 SDK 

thanks in advance, Glen
