* c-common.h (C_MAYBE_CONST_EXPR_PRE, C_MAYBE_CONST_EXPR_EXPR,
C_MAYBE_CONST_EXPR_INT_OPERANDS, C_MAYBE_CONST_EXPR_NON_CONST,
EXPR_INT_CONST_OPERANDS): Remove duplicate definitions.
* c-convert.c (convert): Do not call fold on results of conversion
functions when the result is a C_MAYBE_CONST_EXPR.
* c-parser.c (c_parser_postfix_expression): Do not fold condition
of __builtin_choose_expr.
* c-typeck.c (remove_c_maybe_const_expr): New.
(build_unary_op, build_conditional_expr, build_compound_expr,
build_binary_op, c_objc_common_truthvalue_conversion): Call
remove_c_maybe_const_expr on any input C_MAYBE_CONST_EXPR with
integer operands.
