Don't use static/global variables. They cause a lot of relocation work/size and is less flexible.
In this specific case, I think this array should be const anyway, would that prevent the relocation problems you see?
There is no way to #define ENVL_EEPROM to a function when a variable.
ENVL_EEPROM is an enum value, why would you define it to a function?
