  SEVERITY:  I

  MESSAGE TEXT:  Dependence analysis inhibited due to potential
  overlap dummy arguments and common variables in DO-loop

  EXPLANATION:  Dependence analysis is not performed on DO-loops that
  contain references and stores into dummy arguments and variables in
  a common block.  The potential for dummy arguments and variables in
  common blocks being aliased is the reason for this inhibitor.  This
  error is partially controlled by the setting of the
  /ASSUME=[NO]DUMMY_ALIASES qualifier.
