I assume then that your linux-libc-dev is older than 5.1, which is when that header got introduced?

For the same reason we do not declare Depends on essential packages, or Build-Depends on build-essential packages. I think adding this explicitly for a -dev is fine, and helpful for users, but the environment expected to build stuff in Debian assumes build-essential. > In any case, no matter how you turn it around, it's a package bug. Not necessarily. :) Thanks, Guillem
