* Makefile.in: Add rule for hpux-thread.o (needs special header

	files).
	* (SUBDIRS):  Remove mswin.
	* Change procedure for creating init.c.  Speeds things up quite a
	bit.
	* config.in configure configure.in:  Check for select, poll.
	* Check for OSF header files before including hpux-thread.o.
	* Don't configure doc or testsuite when building under MSVC.
	* findvar.c value.h (read_register_pid write_register_pid):  Make
	global.  Needed for hppa-tdep.c.
	* (supply_register):  Don't set pid to inferior_pid when supplying
	registers.
	* hppa-tdep.c (saved_pc_after_call):  frame_saved_pc ->
	FRAME_SAVED_PC.
	* (frame_saved_pc):  Change name to hppa_frame_saved_pc.
	* (hppa_pop_frame):  Don't use a pid of 0 with target_write_pc.
	Use write_pc instead, which uses the correct pid.
	* (target_read_pc target_write_pc):  Use read/write_register_pid
	instead of read/write_register to preserve the pid passed in.
	* inftarg.c (child_can_run):  Add flag child_suppress_run to allow
	hpux-threads.c to override this as a runnable target.
	* config/pa/nm-hppah.h:  Define target_new_objfile and
	target_pid_to_str.
	* config/pa/tm-hppa.h (FRAME_SAVED_PC):  Use hppa_frame_saved_pc
	instead of frame_saved_pc.
	* config/m68k/tm-m68k.h:  Define TARGET_M68K for Wingdb.
	* config/m68k/tm-monitor.h:  Use FRAME_CHAIN_VALID_ALTERNATE, since
	we can't easily determine the start file bounds with ELF.
	* config/mips/tm-mips.h:  Define TARGET_MIPS for Wingdb.
	* hpux-thread.c:  New file for HPUX/OSF thread support.
	* osf-share/{README AT386/cma_thread_io.h HP800/cma_thread_io.h
	RIOS/cma_thread_io.h cma_attr.h cma_deb_core.h cma_debug_client.h
	cma_errors.h cma_handle.h cma_init.h cma_list.h cma_mutex.h
	cma_sched.h cma_semaphore_defs.h cma_sequence.h cma_stack.h
	cma_stack_int.h cma_tcb_defs.h cma_util.h}:  New files for OSF
	thread support.
