/* Test "ignore redundant include" facility.
We must test with C and 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. */
