Package needs to be fixed into length-unlimited loops.

This comes from ioctls. Fixing this is easy if the structure members
can be expressed by using the _IOT() macro. Else, it's simply
impossible...
> - SA_SIGINFO: 11
Not implemented, packages may be fixed for working around this: use
void sighandler(int num) prototype and sa_handler field.

> - sys_nerr: 2
Package needs to be fixed: sys_errlist should _not_ be used directly,
strerror should be used instead.

Actually fixed in hurd's CVS head.

Not implemented yet.

Mmm, should be fixed with the soundcard.h we now ship in debian.

Linuxish and doesn't even make sense. Fix the package.

Oh, we should probably provide it.

Not POSIX, but we could implement it.

Long story to implement.

Packages should probably not directly use this (not POSIX), but the
POSIX tcgetattr() function instead.
> - PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP: 1
We could easily provide it.
> PTHREAD_STACK_MIN: 1
It's odd we don't have it. IIRC we have a stack minimum: TSD room.
> - net/if_arp.h: 17

Not implemented. POSIX doesn't talk about these.

not POSIX.

Linuxish, there may be more portable ways.

Should include sys/types.h instead. Linuxish if that doesn't work,
and should use stdint.h instead.

Not supported, maybe just a matter of replacing with ioperm(0,65536,1)
(in the GNU case only, it won't work in Linux).
> - 4 pthread_mutex_unlock undefined

Odd, libpthread should provide it.
I won't take the time to go into details of the rest.
