The kernel config files have been changed to use a 'std.i386' file. It
contains the options SWAPPAGER, EXEC_AOUT and EXEC_SCRIPT, which are
non-optional on the i386 (SWAPPAGER isn't optional anywhere).

Also, MACHINE_NONCONTIG has been moved to <machine/vmparam.h> so it
is no longer an 'option'.

You should change your config file to have the line

include "arch/i386/conf/std.i386"

at the beginning of it, in order to catch up with any future changes
to the std.i386 file. All the config files that come with the sources
have been modified to do this.
