There seems to be a change in linux/include/asm/system.h that is causing
linux/net/core/firewall.c to not compile under 1.3.82. When I diff'ed 1.3.77
with the 1.3.82 version, this is what I got:

--- system.h Sun Mar 3 06:14:50 1996

case 1:

When I set the definition back to the "old" version, 1.3.82 compiled cleanly.
