      1 /* Miniature re-implementation of the "check" library.
      2 
      3    This is intended to support just enough of check to run the Expat
      4    tests.  This interface is based entirely on the portion of the
      5    check library being used.
      6 
      7    This is *source* compatible, but not necessary *link* compatible.
