This was forked from #70866. Here’s the relevant portion of what I said at ticket:70866#comment:34:

This warning doesn’t come from gcc. It comes from Apple’s ld, as of Xcode 16 (and the corresponding Command Line Tools version). MacPorts gcc requests this linker: ​lang/gcc14/Portfile. (${prefix}/bin/ld-classic ​is this wrapper that finds and runs ld -ld_classic.)

It’s possible that MacPorts gcc no longer needs the ld-classic workaround as long as ​gcc 0fe7962afc7c is in effect. That change has been cherry-picked as far back as ​gcc-11.
