First and foremost, thanks a lot for working on this and especially for
starting with the enormous task of dealing with the fallout.

Given you probably have the most experience with it, can you please also
suggest an entry to https://gcc.gnu.org/gcc-14/porting_to.html that
would describe this change?  (I was thinking of proposing something
myself, but I don't really know just how much verbose such an entry
should be.)

Thanks!
