  SEVERITY:  I

  MESSAGE TEXT: COMMON block name conflicts with other global entity -
  usage is non-standard and non-portable

  EXPLANATION: The name of a COMMON block is not allowed to be
  the same as the name of any other global entity (program unit,
  external procedure) (F77 standard 18.1.1).  Such a conflict
  may cause incorrect execution on other platforms.

  USER ACTION: Change the name of either the COMMON block or
  the other global entity to remove the conflict.  This
  message can be suppressed by /WARNINGS=NOUSAGE.
