(ISODIGIT, ISSPACE): Remove; now in system.h.
(read_and): Excise ending_file_option.
(decode_header): No need to AND mode with 07777; MODE_FROM_OCT
does this now.
(from_oct): Cast ISSPACE arg to unsigned char.
(mode_from_oct): Translate modes from external to internal form.
Do not complain about unrecognized mode bits.
(decode_mode): Do not assume mode bits have traditional Unix values.
(from_oct): Add forward decl.
(read_header): Return HEADER_FAILURE if we can't parse the checksum.
(from_oct): Report an error only if TYPE is nonzero.
Quote any funny characters in bad header.
size_from_oct, time_from_oct, uid_from_oct, uintmax_from_oct):
Use TYPE_MAXIMUM instead of macros like OFF_MAX, which are not reliable
(e.g. OFF_MAX in AIX 4.2 is incorrect).
print_for_mkdir): Use mode_t, off_t, size_t when appropriate. Remove
now-useless casts. Use unsigned long to print *_t types, except use
STRINGIFY_BIGINT for off_t.
(read_header): Check for overflow when converting header size.
(from_oct): Now static. Now returns uintmax_t. `where' arg is now
const char *. Size arg is now size_t. Now takes new type and maxval
args. Compute result using uintmax_t, not long. Report error if
field does not contain octal number in range.
(gid_from_oct, major_from_oct, minor_from_oct, mode_from_oct,
off_from_oct, size_from_oct, time_from_oct, uid_from_oct,
uintmax_from_oct): New functions.
(stringify_uintmax_t_backwards): New function.
(decode_mode, print_for_mkdir): Mode arg is now mode_t.
(skip_file): Offset arg is now off_t.
