config: prevent the re-definition of a macro 

This causes unnecessary warnings when building with `cl`.  Newer
versions of the C standard permit the redefinition of the macro to the
same value (which is the case here), unfortunately, `cl` does not yet
implement this.  Add a check to prevent the redefinition.
