Teensy: Wire and i2c_t3 conflict

I'm pulling my hair out trying to migrate a project from an Uno to a Teensy 3.2.  I've stripped the project down to nothing but the ino file and no calls to anything serial-related, but I still get the following error:

Wire.cpp.o:In function `i2c0_isr
Wire.cpp:multiple definition of `i2c0_isr
i2c_t3.cpp.o:D:\Program Files (x86)\Arduino\hardware\teensy\avr\libraries\i2c_t3\i2c_t3.cpp:1232: first defined here

I don't remember the option settings to get a verbose build, but I'm pretty sure I've just missed something.  Help is requested and appreciated.  A ZIP of the full project directory is attached.

No, the sketch doesn't run in the straight Arduino IDE (1.6.5), either.  So it's not the Visual Micro add-on.  It's got to be something I'm getting cross-threaded with the i2c_t3 substitute for Wire.  My reason for posting here, instead of the Teensy forum, was to seek advice on clearing out the hidden leftovers VS creates, which ran me in circles last time.  I've deleted all VS files I can find, but I remember there was another file last time I had to delete.
