--- Comment #30 from Jonathan Wakely <redi at gcc dot gnu.org> --- So far the only FAIL is still see is: FAIL: 23_containers/vector/types/1.cc -std=gnu++98 (test for excess errors) I'm not sure if this is caused by your patch or one of Honza's. The test only fails with GLIBCXX_TESTSUITE_STDS=98 defined.
