The newer version (8.2_p1) only has errors about prototypes: /var/tmp/portage/sys-libs/readline-8.2_p1/work/readline-8.2/text.c:1767:1: error: a function definition without a prototype is deprecated in all versions of C and is not supported in C2x [-Werror,-Wdeprecated-non-prototype] I have a patch ready for the issues of that version (haven't backported the fix for the error above yet).
Please ignore comment 8, I cannot reproduce both the error in that comment (comment 8) and i also cannot reproduce the error stated in the bug title with clang-common-15.0.6[stricter].
