-fomit-frame-pointer in this context is only an optimization to gcc itself, not it's output. Does this optimization or lack of it really make a difference for our intermediate compiler? -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
