* c-common.c (boolean_increment): New function.
* c-common.h (enum c_tree_index): Add CTI_C_BOOL_TYPE,
CTI_C_BOOL_TRUE and CTI_C_BOOL_FALSE.
(c_bool_type_node, c_bool_true_node, c_bool_false_node): Define.
(boolean_increment): Declare.
* c-convert.c (convert): Allow for BOOLEAN_TYPE.
* c-decl.c (init_decl_processing): Create boolean nodes.
(finish_struct): Allow for _Bool bitfields.
* c-parse.in (reswords): Add _Bool.
(rid_to_yy): Allow for RID_BOOL.
* c-typeck.c (default_conversion): Make booleans promote to int.
(convert_arguments, build_unary_op, build_modify_expr,
convert_for_assignment): Allow for booleans.
* ginclude/stdbool.h: Make conforming to C99.
cp:
* typeck.c (build_unary_op): Use boolean_increment from
c-common.c, moving the relevant code there.
testsuite:
* gcc.dg/c99-bool-1.c: New test.
