This means IPFIREWALL_DEFAULT_TO_ACCEPT is not defined when
/sys/netinet/ip_fw.c is compiled.

Do you have "options INCLUDE_CONFIG_FILE"?  If so, does
"options IPFIREWALL_DEFAULT_TO_ACCEPT" show up in your kernel?

Does /usr/obj/usr/src/sys/<<KERNELNAME>>/opt_ipfw.h or
/sys/compile/<<KERNELNAME>>/opt_ipfw.h include the lines:
#define IPFIREWALL 1
#define IPFIREWALL_DEFAULT_TO_ACCEPT 1

Does the kernelname in your dmesg.boot match your expected config?

Have you wiped /usr/obj[/usr/src/sys/<<KERNELNAME>>] or /sys/compile
and re-built the kernel?

Have you tried wiping /usr/src[/sys], re-extracting/cvsuping and re-building?

What version is this kernel?

I gather from this that you are using the "old" kernel build strategy.
You are aware that this is missing a step:  Neither "make depend" nor
"make install" actually compiles the kernel.  You need to do a "make"
in between.
