Yes, I think that is probably the best solution. As far as I can tell, at least in this file and context, the warning appears harmless, as the "create a GNU C statement expression from two different macros" is very much intentional, based on the presence of PERL_USE_GCC_BRACE_GROUPS. The warning is fixed in upstream Perl by just avoiding creating GNU C statement expressions using STMT_START and STMT_END:
https://github.com/Perl/perl5/issues/18780 https://github.com/Perl/perl5/pull/18984
If I am reading the source code correctly, an alternative to disabling the warning would be specifying -DPERL_GCC_BRACE_GROUPS_FORBIDDEN but it seems like that might end up impacting more than just this site, according to the issue discussion above.
Cheers, Nathan
