Error compiling ipfw2 on FreeBSD 4.11-RELEASE and 4.11-p10

[Paul Hamilton]

Hi,
 
I have upgraded from FreeBSD 4.7 to 4.11-RELEASE via booting from CD 1.
 
I have IPFW2 options already set in my kernel config file, and in
/etc/make.conf
 
Next, I recompile the kernel, and install it.  Then I went to the
/usr/src/sbin/ipfw dir:-
 
/usr/src/sbin/ipfw-121 <mailto:phroot at ant[7:19pm]/usr/src/sbin/ipfw-121> #
make clean
rm -f ipfw ipfw2.o ipfw.8.gz ipfw.8.cat.gz
/usr/src/sbin/ipfw-122 <mailto:phroot at ant[7:19pm]/usr/src/sbin/ipfw-122> #
make -DIPFW2
cc -O -pipe  -Wall -DIPFW2    -c /usr/src/sbin/ipfw/ipfw2.c
/usr/src/sbin/ipfw/ipfw2.c: In function `list':
/usr/src/sbin/ipfw/ipfw2.c:1698: warning: `last' might be used uninitialized
in this function
cc -O -pipe  -Wall -DIPFW2     -static -o ipfw ipfw2.o 
gzip -cn /usr/src/sbin/ipfw/ipfw.8 > ipfw.8.gz
/usr/src/sbin/ipfw-123 <mailto:phroot at ant[7:19pm]/usr/src/sbin/ipfw-123> # l

I have also tried running 'make' by itself (with out the -DIPFW2 switch)
 
So just as a test, I tried doing the same thing from another FreeBSD
4.11-p10 server (IPFW2 was installed during the buildworld-installworld
process).  I got the same error when manually trying to compile IPFW2!  I
have never had a problem before.
 
What am I doing wrong here?  Any clues?
 
Cheers,
 
Paul
