Add check whether the same constant var_external variable is initialised with two (or more) different constant values.
(* Test whether the keyword XXXX may be used as an identifier for:
 * enumeration value
 *
 * The XXXX names in the following code are merely a placeholder.
 * They will be replaced by several identifiers before actual testing
 * of the compiler.
 *)

(* The identifiers that will replace the XXXX
 * must be placed on a line starting with #
 * All identifiers preceded by # are ignored!
 * The identifier list must be placed inside an IEC 61131-3 comment.
