3269 * c-typeck.c (build_unary_op): Pass original argument of
3270 TRUTH_NOT_EXPR to c_objc_common_truthvalue_conversion, then remove
3271 any C_MAYBE_CONST_EXPR, if it has integer operands.
3272 (build_binary_op): Pass original arguments of TRUTH_ANDIF_EXPR,
3273 TRUTH_ORIF_EXPR, TRUTH_AND_EXPR, TRUTH_OR_EXPR and TRUTH_XOR_EXPR
3274 to c_objc_common_truthvalue_conversion, then remove any
3275 C_MAYBE_CONST_EXPR, if they have integer operands. Use
3276 c_objc_common_truthvalue_conversion not
3277 c_common_truthvalue_conversion.
3278 (c_objc_common_truthvalue_conversion): Build NE_EXPR directly and
3279 call note_integer_operands for arguments with integer operands
3280 that are not integer constants.
