   4  *      ExportElmt list set up during  parse.
   5  *      (not kept in Module data struct)
   6  *
   7  *  SetExports runs through type, value & macro defs and sets the
   8  *  exported flag accordingly.
   9  *
  10  *  The exportsParsed boolean means whether the symbol "EXPORTS"
  11  *  was parsed - since if EXPORTS was parsed and the export list
  12  *  is empty, NOTHING is exported, otherwise if the "EXPORTS"
  13  *  symbol was not parsed (export list is empty) then EVERYTHING
  14  *  is exported.  If "EXPORTS" was parsed and the list is not
  15  *  empty, then mark each item is the list as exported and the
  16  *  rest (that are not in the list) as not exported.
