The problem is, it seems, that it includes sys/disklabel.h when it
should have included machine/disklabel.h instead.  Also, that file
lacks an assembly definition of the symbol d_end_.  Just to get it
assembled properly, so I could get on with things,, I limited my local
modification to the file start.s, thus:

Index: start.s

The basic difference is this: hackers build things, crackers break them.
