NEEDNONCONST

Message        <Context> "<expression>" has const-qualified type,
               but occurs in a context that requires a modifiable
               lvalue.

Description    The code has attempted to modify an object that is
               either a const-qualified type or has been declared
               with the readonly storage-class modifier.  This is
               not valid.  A typical example is assigning a value to
               a const variable.

User Action    Either remove the const qualifier from the object's
               type, remove the readonly storage-class modifier from
               the object declaration, or rework the code so that
               the object is not written to.
