  22 /* If compiling with DECC, need to fix problem with <stdio.h>
  23    which defines a macro called FILE_TYPE that breaks "tree.h".
  24    Fortunately it uses #ifndef to suppress multiple inclusions.
  25    Three possible cases:
  26         1) <stdio.h> has already been included -- ours will be no-op;
  27         2) <stdio.h> will be included after us -- "theirs" will be no-op;
  28         3) <stdio.h> isn't needed -- including it here shouldn't hurt.
  29    In all three cases, the problem macro will be removed here.  */
