Using linux kernel headers directly within a userspace
application (i.e. #include <linux/foo.h>) is illegal.
Therefore, ipfwadm-2.3.0 as shipped, is completely broken.

Look at
    http://ftp.debian.org/debian/pool/main/i/ipfwadm/ipfwadm_2.3.0-4.diff.gz

for an example showing how to fix ipfwadm-2.3.0 so it works
with both glibc and uClibc.
