Message        The type "<type>" has been declared within and is
                limited to a function prototype scope.  It will not
                be compatible with an identical type declared in
                another scope.  This might not be what you intended.

 Description    A type is declared within a function prototype.  The
                type is local to the function prototype and will not
                be visible outside the prototype.  This might cause
                unexpected errors later in the compilation.

 User Action    Declare the type before the function prototype.
