 Message        The type of the tentatively-defined array "<name>" is
                incomplete at the end of the compilation unit.  The
                compiler will assume one array element.

 Description    The C standard requires that the type of all
                tentative definitions must be completed before the
                end of the compilation unit.  For compatibility with
                some other C compilers, Compaq C will give the array
                one element.

 User Action    Complete the type.
