Hi! I just noticed the inetutils build failure on the Hurd, and tracking it down found:
<https://salsa.debian.org/glibc-team/glibc/blob/sid/debian/patches/hurd-i386/local-no_unsupported_ioctls.diff> While I've prepared a patch to fix this, I think it might be better (instead or in addition) to disable the ioctls and the matching ioctl options. For example in inetutils, the code works on GNU/Linux because it's checking whether LNOFLSH is defined, and if so then it uses TIOCLGET. Thanks, Guillem
