Building cpio with GCC 14 fails here:
https://build.opensuse.org/package/live_build_log/openSUSE:Factory:Staging:Gcc7/cpio/standard/x86_64

Due to:

util.c: In function ‘tape_fill_input_buffer’:
util.c:204:12: error: implicit declaration of function ‘tape_eof’ [-Wimplicit-function-declaration]
  204 |       if (!tape_eof (in_des))
      |            ^~~~~~~~
util.c:209:15: error: implicit declaration of function ‘tape_eod’ [-Wimplicit-function-declaration]
  209 |           if (tape_eod (in_des))
      |               ^~~~~~~~
