error: reference to 'Print' is ambiguous

[humanusdeus]

Can't compile the code examples, it always outputs the error:

Hi there,

Looking at the last line of your output, I'm experiencing the identical error.

I'm attempting to compile against a Nano Every.

My sketch runs fine on a Pro Micro and Mega.

Cheers.

I had to remove the 'class Print' forward declarations from the following files:
DMS.h
NeoTime.h

Also had to set SPI_DRIVER_SELECT to 1 per greiman/SdFat-beta#42

Additionally, changed '#define F(str) (str)' in Arduino.h to '#define F(str) (const __FlashStringHelper*)(str)'

It at least now compiles, though I don't have my Every available until end of the week to test uploading and execution.
