 Message        <Context> using __ALLOCA and variable-length arrays
                in the same function is not allowed on this platform.
                The first variable-length array declaration is at
                <where>.

 Description    Because they place different requirements on stack
                allocation on VAX systems, __ALLOCA and
                variable-length arrays cannot be used in the same
                function.

 User Action    Recode the function to use either variable-length
                arrays or __ALLOCA.
