/* Test "ignore redundant include" facility.

   We must test with C comments, and null directives, outside

   the guard conditional; also, we test guarding with #ifndef and #if

   !defined.  -H is used because cpp might confuse the issue by

   optimizing out #line markers.  This test only passes if each of the

   headers is read exactly once.

   The disgusting regexp in the dg-error line, when stuck into

   dg.exp's compiler-output regexp, matches the correct -H output and

   only the correct -H output.  It has to be all on one line because

   otherwise it will not be interpreted all in one unit.  */
