--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I've hacked up my libgfortran/configure, added there sleep 60s after writing conftest.c for working stat check, and then rm -f config.cache; ./config.status --recheck in the x86*/32/libgfortran directory and the above conftest.c is what I saw.
