As I mentioned today on bug-gnulib I installed some changes into Gnulib which are related, and it'd probably be better to sync with the latest version. (Unfortunately I didn't know about your changes, so there was some overlapping work here.)

I don't see why this change is needed, as the only use of that macro is in "#if !FUNC_REALPATH_WORKS || defined _LIBC", which is unaffected by this change since _LIBC is defined.

This change isn't needed, since end_idx is used only when end_in_extra_buffer is true.
Was the latter change put in only to pacify older GCC versions? (I don't get a warning with GCC 10.2.) If so, we should do the initialization only for those older versions; or Gnulib has a GCC_LINT feature for this sort of thing.
