I'll need to update that to more current gcc anyway (and see if that takes care of sh/sh64), so if you can dig those .spec out... throw them my way and I'll add them to repository. How well do they handle the targets for which you have no glibc-dev binary rpms, BTW? I needed headers for ia64 and ppc64; both fortunately are among the generally supported targets... -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
