i agree people shouldnt be invoking the linker directly, and that it is easy to convert to the gcc compiler driver, but i have seen a package or two invoke it directly and i imagine there's a few more. breaking what is technically valid code (even if by taste, they suck) wont fly in general :/. -mike _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
