--- Comment #7 from Gaius Mulley <gaius at gcc dot gnu.org> --- I doubt the m2date and testclock are related to filesystem case (but I could be wrong) as I've built gcc on a gnu-linux jfs filesystem (case preserving case insensitive) and see: === gm2 Summary === # of expected passes 13034 no failures. Just though this is an interesting data point.
