i just got libc6 2.2.3-10 compiled, and, i seem to be getting the missing atexit symbol problem again... although i haven't run across any debian compiled stuff, my copy of quake2, and the copy of quakeforge i compiled are both failing, although the latter is failing because /usr/X11R6/lib/libXxf86dga.so is missing atexit, so i suppose that counts as a debian package problem...
just thought i'd mail a heads up, as it's not critical for me yet, but i recall having this issue a while back... Andrew 'ashridah' Pilley (and yes, i know stictly speaking that this is a libc6 problem, not a gcc problem, but hey, ben collins reads this list right? :) )
