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 if the       definition itself provides a prototype. The aim is to detect       global functions that fail to be declared in header files.       
Whereas -Wmissing-declarations does:
       Warn if a global function is defined without a previous       declaration. Do so even if the definition itself provides a       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?
