OK, here they are. I've tested both only on i386 (I don't have any other arch right now). They seem to work fine (pass build-id by default, can be overridden with -Wl,--build-id=none). I've also put gcc-4.3 in my chroot and built a couple of packages (rarian and libsoup2.4), both built successfully. The patch is the same from gcc trunk, not the one Fedora uses. How do they look? Thanks, Emilio
