Dear Jo, the error you observe comes from libraries/Wire/utility/twi.c. This is not the stock version under the "hardware" tree, which has not "utility" subdirectory. I would suggest, you move away C:\Users\wildcat\Documents\Arduino\libraries\Wire\, restart the arduino ide, and try the minimal example again.
Hope this helps!
Looking at the tree, I realized that it was still trying to associate with the libraries from previous IDE versions that I thought I had deleted. Once directories were correctly associated, the correct libraries worked.
Thanks for pointing that out,
