* fork-child.c (fork_inferior), remote-eb.c (eb_create_inferior), 

remote-mon.c (monitor_create_inferior), remote-nindy.c
	(nindy_create_inferior), remote-st.c (st2000_create_inferior),
	remote-vx.c (vx_create_inferior): Remove CREATE_INFERIOR_HOOK; it
	is replaced by init_trace_fun.
	* config/convex/xm-convex.h, convex-xdep.c: Add comments explaining
	how to do without CREATE_INFERIOR_HOOK for whoever fixes the Convex
	port.

	* Makefile.in: Add Mach files to ALLDEPFILES, etc.
	* m3-nat.c: Clean up more hair--message(), cprocs.
	* configure.in: Recognize Mach targets and hosts.
	* config/ns32k/tm-umax.h: Add some #ifndef's so tm-ns32km3.h can
	include this file.
	* Mach headers in config/*/tm-*.h: Fix includes to match correct
	locations of files.
