--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I use the same dejagnu and they don't fail. And looking at e.g. the gcc-testresults mailing lists, they don't fail for others either (there are some pch/embed-1.c failures in freebsd results but that looks like PCH issue on FreeBSD, not anything else, and some issues on AVR (but I assume that is because of 8-bit int, which is not valid in C). Are you configuring in the source directory, or using some custom board file to override stuff?
