-Wmissing-declaration should do what you want.

What is the difference between Wmissing-prototypes and Wmissing-declarations?

 -Wmissing-prototypes (C and Objective-C only)
           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.

       -Wmissing-declarations
           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.  In C++, no
warnings are issued
           for function templates, or for inline functions, or for functions in
anonymous namespaces.


They seem exactly the same thing!

So Joseph, Jason, what is the difference between Wmissing-prototypes and
Wmissing-declarations?

Can't you just make one a synonym for the other and make one of them the
canonical form?

C++ doesn't have prototypes, it has declarations and definitions, so the
different names makes sense.

I'm not sure what "Do so even if the definition itself provides a prototype."
means in the context of C++.

That's simple enough: it's a style warning: a global function should be 
declared in a header, so warn for

int
f (void)
{
  return 0; 
}

if there was no previous declaration for f.  (For C++, the definition and 
any previous declaration will always provide a prototype.)

As Ian said in <http://gcc.gnu.org/ml/gcc/2011-08/msg00366.html>, for C++ 
the two options reduce to the same thing because no non-prototype 
declarations or definitions exist.  For C,

int f();
int f(void) { return 0; }

gets a warning with -Wmissing-prototypes but not -Wmissing-declarations, 
because "int f();" is a non-prototype declaration in C.

I get that part.

>  (For C++, the definition and 
> any previous declaration will always provide a prototype.)

Exactly, that's my point.  But I had missed the fact that the option is valid
in C as well as C++.

My uncertainty was about what that sentence means in the context of C++, and
the answer is nothing, because there are no definitions which do not provide a
prototype in C++ (ignoring the fact that "prototype" doesn't mean anything in
C++).

I will update invoke.texi to make this clear. I see a lot of confusion among
users:

Honestly, I don't see the purpose of this distinction in modern C. I would
rather have -Wmissing-declarations be an alias of -Wmissing-prototypes in C,
and simplify both GCC and the life of users.

Jon, I'd like to resolve this PR: personally I totally agree with Manuel that
adding a few words of clarification in the docs, in particular explaining that
"prototype" is a C concept, is a good idea, but I'm not 100% sure about the
English. Could you double check the tentative patch here in the audit trail and
possibly post it to the mailing list?
