So far, support for wrong-location headers like <sys/errno.h> is
inconsistent; we support some of them but not others. The long-term
plan is to support all of the ones glibc does, but with #warning in
the wrong version of it. I think you should report the bug upstream
and try to get it fixed. It's definitely been more than 20 years since
there was a system where <sys/errno.h> was needed, and I doubt such
systems existed even back then.

As for <sys/ttydefaults.h>, I'll look at it. I'm not familiar with
what it's for. But it seems unused...
