   The problematic code is in gnulib, which inetutils pulls in at build   
   time. This has been fixed in upstream gnulib at least with commit   
   df17f4f37ed3ca373d23ad42eae51122bdb96626 (there might be other commits   
   needed besides that though).   
      
   There was a gnulib upload with a recent version that I think should   
   contain the fixed code, which looks being intended for experimental,   
   but ended up in unstable, and even though the buildd status says it   
   supposedly got built, it does not appear on unstable.   
      
     https://tracker.debian.org/news/1706111/accepted-gnulib-202601   
   9-1exp1-source-into-unstable/   
     https://buildd.debian.org/status/package.php?p=gnulib   
      
   I tested with a local checkout (from today) of gnulib and the glibc   
   from experimental, and inetutils then builds fine. So a fixed gnulib   
   should fix the inetutils FTBFS.   
      
   Once a fixed gnulib is uploaded, it might also make sense to add a   
   version Breaks from libc6-dev against gnulib probably.   
      
   Thanks,
