>Description:
When outputting errors, in some cases ipfw tries to print av instead of *av, which causes 4 (sizeof(char *)) "random" bytes to be printed. Does not crash, because av ends with '\0'.

After this fix, "WARNS?=0" in the Makefile is no longer needed.

>How-To-Repeat:
ipfw add 100 allow ip from any to any proto foo
ipfw add allow proto boo

>Fix:
cd /usr/src/sbin/ipfw
cat /tmp/ipfw2.c.patch |patch
make && make install
