re PR c++/11957 (wrong "warning: statement has no effect")
cp:
PR c++/11957
* cp-tree.h (finish_stmt_expr): Add bool parameter.
* init.c (finish_init_stmts): Pass true to finish_stmt_expr. Don't
adjust the stmt_expr here.
(build_vec_init): Use finish_stmt_expr_expr, convert result to
array type.
* parser.c (cp_parser_primar_expression): Adjust finish_stmt_expr
call.
* pt.c (tsubst_copy): Likewise.
* semantics.c (finish_stmt_expr): Add parameter.
testsuite:
PR c++/11957
* g++.dg/warn/noeffect1.C: New test.
