/* Test "ignore redundant include" facility.
-H is used because cpp might confuse the issue by optimizing out
#line markers. This test only passes if the headers is read
twice.
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. */
