The "git" didn't try store small variables, which aren't referenced, in the processor registers. It also didn't use the size_t type. I corrected a C++ style comment too.

Well, modern compilers take register as a non-binding hint. Your register storage specification for those loop counters will not make any change. You have not looked into the resulting binary?

Also // is valid C99 ...


But if you use only /* */ comments and there's a // comment it looks ugly :).

I've disassembled the code and it for me (I'm not a professional assembler coder) it looks like it's stored in a register because the ebp offsets are smaller and the gcc (4.0) wouldn't cause an error if you reference them.
