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

 Message        <Context> a required set of braces is missing.

 Description    The initializer for this union was not enclosed in
                braces.  While some compilers allow this, standard C
                requires braces around the initializer.

 User Action    Enclose the initializer in braces.
