  10    Note that because the barrier construct does not have a C language
  11    statement as part of its syntax, there are some restrictions on its
  12    placement within a program. The barrier directive may only be placed
  13    in the program at a position where ignoring or deleting the directive
  14    would result in a program with correct syntax.  */
