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?
