gcc15_tinderbox has reproduced this issue with version 2024-r1 - Updating summary.

[Comment 3 Sam James 2024-12-24 05:03:12 UTC]

I'll add -std=gnu17 for now, I still have handling C23 porting for various TeX stuff WIP locally.

    app-text/texlive-core: build w/ -std=gnu17
    
    I have drafts for some (not all yet) for TL for C23 porting. I need
    to report this upstream still but ideally with a patch.

command-line option '-std=gnu17' is valid for C/ObjC but not for C++
so:

-       append-flags -std=gnu17
+       append-cflags -std=gnu17

    app-text/texlive-core: append-flags -> append-cflags
    
    Apparently there's some C++ in TL.
