The make O=$PWD truncates the Makefile, making it necessary to run `git checkout Makefile` - should you have git; or reextract the tarball (should you /still/ have it). Well, can we catch this case somehow? thanks, Jan - 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/
