Marchesi <jemarch at gcc dot gnu.org> --- > The commit r16-7016-g9c8bb50ab9896924a95af78c345c301c36224fb6 should > result in libgc to not be used at all in systems where the system is > not recent enough to provide GC_is_init_called. Unfortunately, this is still not right: When you configure with --with-target-bdw-gc* (e.g. when bdw-gc isn't available on the system at all), that is used unconditionally even if too old. With enable_algol68_gc = auto, it should just be ignored and Algol68 GC disabled. As is, the build still breaks in this case.
