First of all, the kernel Makefiles contain a hack which force -fno-strict-aliasing whether you want it or not. Second, the kernel will *not* build without -fno-strict-aliasing, partly because of preexisting aliasing violations and partly because of aliasing violations which were introduced after the hack (and could have been avoided if that hack had not been in place). > There's a dozen or two files that will fail to compile -O2 w/o it > spread through the tree. not throughout the tree - only in the kernel.
