Ah! Yes, with 2.4 on xeno.2.1 we have to take care of all compiler arguments on our own. You certainly know of some out-of-tree PPC-specific drivers. Could you check if they use other special switches? Is this specific for the mpc8xx? Do you see a clean, generic solution? Feel free to patch configure.ac when you think you found one. Jan
