--- Comment #6 from David Malcolm <dmalcolm at gcc dot gnu.org> --- (In reply to Bernd Edlinger from comment #5) > this seems to fix it: Thanks, and sorry for the breakage. I wonder if it would be better to instead hardcode LANG=C in the Makefile.am hooks that run the selftests? The DejaGnu-based testsuite does that.
