Macro expansion bug in gcc?

[Neil Booth]

The following test case appears as gcc.dg/200000209-2.c

#define NO_PAREN(rest...) rest
#define DEFINE_CATEGORY(category, items) \
const int _nl_value_type_##category[] = { NO_PAREN items }

DEFINE_CATEGORY
(
 LC_COLLATE,
 (
   1,
   2,
   3,
  ));

Current gcc outputs (modulo new lines)

const int _nl_value_type_LC_COLLATE [] = { 1, 2, 3, } ;

A new macro expander I'm trying out gives:-

const int _nl_value_type_LC_COLLATE[] = { NO_PAREN ( 1, 2, 3, ) };

I believe that current gcc is wrong and that the new code is right.
Would someone agree or disagree?

Thanks,

Neil.
