 Message        <Context> "<name>" has no linkage and has a prior
                declaration in this scope at <where>.

 Description    A declaration within a function body redeclares an
                identifier declared earlier in the current scope, and
                both declarations did not have the extern storage
                class.

 User Action    Either remove the extra declarations, or have all
                declarations for the identifier use the extern
                storage class.
