#include <vm/vm_param.h> instead of <machine/vmparam.h> (the former

Browse Source 
includes the latter, but also declares variables which are defined
in kern/subr_param.c).

Change som VM parameters from quad_t to unsigned long.  They refer to
quantities (size limits for text, heap and stack segments) which must
necessarily be smaller than the size of the address space, so long is
adequate on all platforms.
