Also, I see
FAIL: c-c++-common/spec-barrier-1.c -Wc++-compat (test for excess errors)
FAIL: c-c++-common/spec-barrier-1.c -std=gnu++11 (test for excess errors)
FAIL: c-c++-common/spec-barrier-1.c -std=gnu++14 (test for excess errors)
FAIL: c-c++-common/spec-barrier-1.c -std=gnu++98 (test for excess errors)
If some targets are expected to emit a warning on this test and you don't
want to maintain exact list of targets which warn in the testsuite,
shouldn't the test use -w in dg-options?
