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.
