/sys$common/syshlp/helplib.hlb CC, Messages, PROTOSCOPE3  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        <Context> the struct type was previously declared in
                this function with prototype scope.  Now it is
                declared with file scope.

 Description    This message is generated when the compiler first
                encounters a function prototype that declares a type
                with prototype scope, and then later sees a second
                declaration or definition of that same function with
                the parameter declared using the same type declared
                at file scope.  For example:  void foo(struct S { int
                a; int b;} *s); struct S { int a; int b;} s; void
                foo(struct S *s);

 User Action    Declare the type at file scope before the first
                prototype declaration.
