bind (and ~8 other packages IIRC) were poisoned by a change in the
definitions generated when invoked with "-m486". The change, defining
__i486__, caused the inline assembly for ntohl/ntohs to use an i486
instruction that is illegal on i386 to be compiled in. The problem is
(or will be) fixed in the compiler. Meanwhile, recompile bind (and
other packages) from src.rpm's making sure that rpm optflags does not
set -m486.

Here's the list of affected packages:
	arpwatch-2.1a4-10
	bind-8.2-6
	bind-utils-8.2-6
	dip-3.3.7o-14
	dosemu-0.99.10-4
	ftp-0.10-22
	guavac-1.2-4
	ipchains-1.3.8-3
	knfsd-1.3.3-1
	knfsd-clients-1.3.3-1
	mars-nwe-0.99pl15-3
	routed-0.10-14
	rpm-3.0.1-12
	rpm2html-1.1-2
	strace-3.99-1
	tcpdump-3.4-10
	xboing-2.4-7
	ytalk-3.1-3


Here's the script (from Alan Cox) that was used to detect "poisoned"
i386 packages:

#!/bin/sh

for i in $*; do
        X=`file $i`
        echo -n $i
        case "$X" in
                *ELF*)
                        (objdump --disassemble $i  2>/dev/null)|grep
bswap >/tmp/x1
                        if [ -s /tmp/x1 ]; then
                                echo " contaminated"
                        else
                                echo " ok"
                        fi
                        ;;
                *)
                        echo " not ELF"
        esac
done
