Another try - same error message

[Steve Zielinski]

build/vendor/cmock/src/cmock.c:
    28: static long long CMock_Guts_Space[((32768) + (size_t)(1u << (2)) + sizeof(long long) - 1) / sizeof(long long)];
                         ^ (1516) compiler does not support 64-bit integers on the target architecture (warning)
Non line specific message: (1091) main function "_main" not defined

In the case above I was trying to follow jmrubillon/Ceedling_xc8: Sample project for using ceedling with Microchip's xc8 compiler (github.com)

I'm back to the same spot without an idea how to fix it.
