re PR c++/56239 (parse error calling operator() on parenthesized value-initialized temporary)
PR c++/56239
* parser.c (cp_parser_token_starts_cast_expression): Renamed to...
(cp_parser_tokens_start_cast_expression): ... this. Change parameter
to cp_parser *, call cp_lexer_peek_token first. For CPP_OPEN_PAREN,
return true only if 2nd token isn't CPP_CLOSE_PAREN.
(cp_parser_cast_expression): Adjust caller.
* g++.dg/parse/pr56239.C: New test.
