State-Changed-Why:
    While I believe that your original example is not very
    good since the forward declarating a function as "inline"
    does not make a difference, the following snippet indeed
    has an example where foo() is not inlined and -Winline
    does not give a message:
    --------------------------
    #include <setjmp.h>
    
    inline void foo() {setjmp(0);};
    int main(int, char**)
    {
      foo();
      return 0;
    };
    -------------------------
    This holds for all gcc versions I have. The assembler
    output clearly shows that foo() is not inlined.

    Fixed in GNU C++ version 3.4 20030429 (experimental)
    Heck, I even get a warning for a system header function!
