We've always used -Wmissing-prototypes. The documentation states that
-Wmissing-prototypes instructs GCC to:
Warn if a global function is defined without a previous prototype declaration. This warning is issued even
ifthe definition itself provides a prototype. The aim is to detect global functions that fail to be
declaredin header files.
Whereas -Wmissing-declarations does:
Warn if a global function is defined without a previous declaration. Do so even if the definition itself
providesa prototype. Use this option to detect global functions that are not declared in header files.
Which doesn't make the difference in behavior between the two options
clear to me. Can anyone clarify this?
BTW, are these changes appropriate for 8.0?
