c-typeck.c (default_function_array_conversion, [...]): Allow for CONVERT_EXPR as well as NOP_EXPR.
* c-typeck.c (default_function_array_conversion,
build_function_call): Allow for CONVERT_EXPR as well as NOP_EXPR.
(build_conditional_expr): Apply integer_zerop to orig_op1 and
orig_op2. Don't check them for NOP_EXPR.
(build_c_cast, convert_for_assignment): Don't check for NOP_EXPR
around integer zero.
testsuite:
* gcc.dg/c90-const-expr-4.c, gcc.dg/c99-const-expr-4.c: New tests.
