FreeBSD fbsdsendpr.lackaday.org 8.2-RC1 FreeBSD 8.2-RC1 #0: Fri Dec 31 02:44:56 JST 2010     builder at fbsdsendpr.lackaday.org:/usr/src/sys/i386/compile/GENERIC  i386

>Description:
 The kernel options COMPAT_FREEBSD[456] depend on COMPAT_FREEBSD7
in different from natural understanding.
I think they should be independent each other.

>How-To-Repeat:
 Copy GENERIC kernel config and comment out "options COMPAT_FREEBSD7" line,
then try to build a kernel with the config file.
See the above "Full Description".
