Fix these class of warnings: - unused functions - unused locals - sign mismatch - missing function prototypes - missing newline at end of file - 64 to 32 bit truncation The changes prefer to link in dead code in the debug build with 'if (false)' than to comment it out, but trivial cases are commented out or sometimes deleted if it appears to be a copy/paste error.
