* c-common.h (enum c_tree_index): Add CTI_C_SIZE_TYPE.
(c_size_type_node): Define.
* c-decl.c (init_decl_processing): Initialize c_size_type_node.
* c-common.c (enum format_lengths, enum format_std_version,
format_length_info, format_type_detail, BADLEN, NOLENGTHS,
format_kind_info, printf_length_specs, scanf_length_specs, T89_I,

format_types): Define.
(format_char_info, print_char_table, scan_char_table,
time_char_table): Rearrange for new organization of information
about format length modifiers and standard versions.
(T_ST): Redefine to use c_size_type_node.
(check_format_info): Obtain information about length modifiers and
standard versions from tables. Adjust warning message wordings.
Use the name from the user's program for `ll' and `hh' length
modifiers in warning messages. Use more informative names for
wanted types where available (for wchar_t, wint_t, size_t, signed
size_t, ptrdiff_t, unsigned ptrdiff_t, intmax_t and uintmax_t).
