In a very a.out ish way. Do you know if that support was ever used? If we are truly talking a.out only we should be able to make uselib conditional on a.out support in the kernel which is strongly mostly disabled at this point. I am wondering if there are source trees for libc4 or libc5 around anywhere that we can look at to see how usage of uselib evolved. Eric
