Every one should compile C (no joke inside) with at least :

-Wall -Wextra (or -W for older compilers) -Werror

I also use on every project :

-fstrict-aliasing -Wshadow -Wcast-align -Wwrite-strings -Wsign-compare -Wno-uninitialized -Wpointer-arith -Wredundant-decls -Wbad-function-cast -Wstrict-prototypes -Wmissing-prototypes -Wnested-externs

and also when I have not too many function pointers with unused parameters, also :
-Wno-unused (helps to keep track of old variable you no longer use, and that you can also clean).

Every one should do that. C is a sharp tool, one should not *hope* it works, and keep every chances on his side.
