* tm.texi (INTMAX_TYPE, UINTMAX_TYPE): Define.
* c-common.h (enum c_tree_index): Add CTI_INTMAX_TYPE and
CTI_UINTMAX_TYPE.
(intmax_type_node, uintmax_type_node): Define.
* c-common.c (decl_attributes): If pedantic, warn if `mode'
attributes create a type wider than intmax_t.
(T_IM, T_UIM): Define properly.
* c-decl.c (INTMAX_TYPE, UINTMAX_TYPE): Define if not already
defined.
(init_decl_processing): Initialize intmax_type_node and
uintmax_type_node.
* c-lex.c (lex_number): When pedantic and warning for integer
constants that are too large, in C99 mode warn for those that have
a type wider than long long.
cp:
* decl.c (INTMAX_TYPE, UINTMAX_TYPE): Define if not already
defined.
(init_decl_processing): Initialize intmax_type_node and
uintmax_type_node.
testsuite:
* gcc.dg/c99-printf-1.c, gcc.dg/c99-scanf-1.c,
gcc.dg/c90-printf-2.c, gcc.dg/c90-scanf-2.c: Define intmax_t and
uintmax_t using <limits.h> to emulate the compiler's internal
logic. No longer XFAIL %j tests.
