VMS Help CC, Messages, PROTOTYPEDEF  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        The extracted header file contains prototypes with
                typedefs, which should be moved to after the typedef
                declaration.

 Description    When extracting function prototype declarations, the
                compiler has encountered a parameter type specifier
                that is defined by a typedef.  Because the created
                prototype will use this typedef, it should be moved
                after the typedef declaration in the final
                compilation source.  This message can only be
                generated when the compiler has been invoked with the
                option to extract function prototype declarations.

 User Action    Be aware of this if you wish to use the output .H
                file.
