* printcmd.c (decode_format): Don't blithely set the size for
an address to 'w'. Make it 'g' or 'h', depending on TARGET_PTR_BIT. * defs.h: Just typedef CORE_ADDR to bfd_vma. Include bfd.h. If BFD64, make a LONGEST a BFD_HOST_64_BIT. * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead always just check against INT_MIN and INT_MAX (this also fixes things if sizeof (long) > sizeof (int), e.g. Alpha). * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h: Don't define LONGEST or BUILTIN_TYPE_LONGEST. * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and BUILTIN_TYPE_UNSIGNED_LONGEST. * language.h, c-lang.c, ch-lang.c, m2-lang.c: Remove longest_int and longest_unsigned_int. * value.h (struct value): Just align to LONGEST, rather than worrying about CC_HAS_LONG_LONG. * valarith.c (value_binop, _initialize_valarith): Figure out type ourself based on sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST. The point is that we don't depend on CC_HAS_LONG_LONG anymore. * valprint.c (val_print_type_code_int): Just call extract_unsigned_integer directly, rather than going through unpack_long. * printcmd.c (decode_format): Remove code which would sometimes change 'g' size to 'w' for integers. print_scalar_formatted handles printing huge integers well enough, thank you.

+ * language.h, c-lang.c, ch-lang.c, m2-lang.c: Remove longest_int
+ and longest_unsigned_int.

+
* command.c (add_set_cmd, no_just_help_class_command): Change
to make this the sfunc, not cfunc, since that is how we call it.
* command.h: Comment difference between sfunc and cfunc.
