However I do not know if this applies to the esp8266 port which compiles without error with uint64_t variables. To confirm what is happening I need to be able to print 64 bit integers. Others have also had the need to print 64 bit integers and have written library code for the AVR:

I have ported the code over to esp8266 and have it to the point where it will compile but have not yet confirmed that it works.

I have ported a patch that I found for the AVR library over to the print library for the esp8266. It seems to work well for my needs. Also the Arduino esp8266 language seems to handle 64 bit math OK for my application. The modified library files are attached - use at your own risk.
