--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I think the configure scripts during build are run through $(SHELL) $$s/$$module_srcdir/configure ... from the toplevel makefile, so it doesn't care if it has executable permissions or not. Doesn't hurt to change the permissions of course.
