CONSTSTOCLS

Message        <Context> the const object "<name>" has no explicit
               storage class.  In C, its storage class defaults to
               "extern"; in C++, it defaults to "static".  Add an
               explicit "extern" or "static" keyword.

Description    One of the more signifcant and confusing differences
               between C and C++ is their treatment of file scope
               const objects declared without a storage class.  C
               will give the object extern storage class, making the
               object visible in other compilation units.  C++ will
               give the object static storage class.  This can cause
               an undefined symbol error when other compilation
               units try to reference the symbol.

User Action    Add an explicit "extern" or "static" keyword to the
               declaration.
