    Sorry. They were posted in another thread, but I'll provide them
    again.

    Adding "#include <sys/kernel.h>" *almost* fixes things, but there are
    still some missing defines (from sys/amd64/include/vmparam.h, which is
    not being included either).

    In /etc/make.conf:

    COPTFLAGS= -O2 -pipe -march=athlon64 -m64

    Adding '#include "/usr/src/sys/amd64/include/vmparam.h"' to mem.c (I
    know this is a hack) produces this:

    linking kernel.debug
