Details:
The function eeprom_write_byte() assigns the EEAR with the address passed in
through the __p parameter. This parameter is declared as a pointer type in the
function declaration, and then re-cast to "unsigned" at the assignment of it
value to the EEAR.
when using the -mint8 compiler switch, "unsigned" becomes an 8-bit type,
however, it is being assigned to a 16-bit location. The compiler throws a
warning.
This is easily fixed by changing the "unsigned" casts to the proper
"unint??_t"
Specifically, reference lines 308-312 of eeprom.h
