Patch 204 was designed to fix a specific problem with overflows of user 
defined types in yacc. In the process, a problem was inadvertently introduced. 
If you encounter a problem with yacc after applying patch 204 to your system, 
you may remove it without affecting the Y2K compliancy status of your system.
