    Ensure that the parameter token position is recorded for both
    definition and implementation modules.  The shadow variable
    is created inside BuildFormalParameterSection.  The shadow
    variable needs to have the other definition or implementation module
    token position set when CheckFormalParameterSection is called.
    This allows the MetaError family of procedures to request the
    implementation module token position when reporting unused parameters.

            * gm2-compiler/P2SymBuild.mod (GetParameterShadowVar): Import.
            (CheckFormalParameterSection): Call PutDeclared for the shadow
            variable associated with the parameter.
