Warning Options - Using the GNU Compiler Collection (GCC)
-Wall only turns on -Wsign-compare for in C++ files. If you/we want it for C files, we need to use -Wextra (which we don't have on, but most likely should).
I will leave it to Dragos to decide/comment. Making it compile with -Wextra, will quiet it down in Visual Studio (and other compilers). I'm not sure we can add "-pedantic -std=c11" but we can try -- again, depends on Dragos' schedule/time.
