ENVIRONMENT VARIABLES
       The following environment variables shall affect the execution of link:
       LANG   Provide a default value for the  internationalization  variables

              IEEE Std 1003.1-2001, Section  8.2,  Internationalization  Vari-
              ables  for the precedence of internationalization variables used
