If your compiler does not support long long, there are a whole bunch of
*other* parts of the C standard that it does not satisfy, and you will
probably find that you will fight other unnecessary battles.

One possibility would be to compile CLANG+LLVM for your target. If that
is not possible, perhaps GCC?
