Here's the link for the previous message's spot in the archives:
https://gcc.gnu.org/pipermail/gcc-patches/2023-May/620137.html
Here's an updated (but still untested) version of the patch with an invoke.texi
update and a ChangeLog entry:

gcc/c-family/ChangeLog:

    * c.opt: Have -Wpointer-sign be enabled by -Wextra, too
