+Since the CORBA spec requires that all enums be 32 bits, and some compilers
+will try to use less space if the enum values are small enough, the IDL
+compiler now appends <enum name>_TAO_ENUM_32BIT_ENFORCER = 0xFFFFFFFF to
+every enum. This appended enum value is not part of the IDL compiler's
+internal representation of the enum, so unions that use the enum as a
+discriminator will not have incorrect _default() code generated for them.
