609 # GCC 4.1+ has a stack protection feature that requires OS support. Ubuntu has
610 # it switched on by default, and we use the host compiler, so it compiles AROS
611 # code with this enabled resulting in link failures as we don't have support
612 # for it.
613 #
614 # We use two methods to disable it. For the host compiler (used to compile
615 # some hosted modules), we test to see if the compiler supports stack
616 # protection, and if it does we disable it in AROS_CONFIG_CFLAGS. This should
617 # work on all platforms.
618 #
619 # For the "cross" compiler we clear the "ssp_default" spec in config/specs.in
620 # (this is done unconditionally, as it should have no effect on compilers
621 # without the stack protection feature). This may be specific to the way that
622 # Ubuntu enables the feature, so may not work everywhere. My specs-fu isn't
623 # strong enough to disable it in a generic way though, so we'll live with it
624 # until another vendor ships GCC with it enabled in a different way, and deal
625 # with it then.
