	objfiles.h, infcmd.c, printcmd.c, stack.c, typeprint.c,
	valarith.c, valops.c, valprint.c, value.h, values.c: Replace
	value with value_ptr.  This is for the ptx compiler.
	* objfiles.h, target.h: Don't declare a "sec_ptr" field using a
	"sec_ptr" typedef.
	* symm-nat.c: Add a bunch of stuff for symmetry's ptrace stuff.
	#if 0 i386_float_info.
	* symm-tdep.c (round): Remove.  Also remove sgttyb.
	* symm-tdep.c: Remove lots of stuff which duplicates stuff from
	i386-tdep.c.  Remove register_addr and ptx_coff_regno_to_gdb.
	* i386-tdep.c (i386_frame_find_saved_regs): Put in
	I386_REGNO_TO_SYMMETRY check in case it is needed for Dynix
	someday.
	* config/i386/nm-symmetry.h: Change KERNEL_U_ADDR.  Move
	stuff from PTRACE_READ_REGS, PTRACE_WRITE_REGS macros to
	symm-nat.c.  Define CHILD_WAIT and declare child_wait().
	* config/i386/tm-symmetry.h: Remove call function stuff; stuff in
	tm-i386v.h is apparently OK.
	* config/i386/xm-symmetry.h [_SEQUENT_]: Define HAVE_TERMIOS not
	HAVE_TERMIO.  Define MEM_FNS_DECLARED, NEED_POSIX_SETPGID, and
	USE_O_NOCTTY.
