Package needs to be fixed into length-unlimited loops.

>       - _IOT*: 14

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.

Package needs to be fixed: sys_errlist should _not_ be used directly,
strerror should be used instead.

Not implemented yet: https://savannah.gnu.org/bugs/?18218

"People should not use NOFILE anyway"

Not fixed yet: http://sourceware.org/bugzilla/show_bug.cgi?id=3906

Actually fixed in hurd's CVS head.

>       - SOL_IP: 5

Not implemented yet.

>       - SOUND_MIXER_*: 4

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

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

>       - SIOCDEVPRIVATE: 3

Oh, we should probably provide it.

>       - MAP_NORESERVE: 2

Not POSIX, but we could implement it.

>       - O_DIRECT: 2

Long story to implement.

>       - TCGETS: 2 
>       - TCSETS: 1 

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.

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.

>       - 4 iopl undefined

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

Odd, libpthread should provide it.

I won't take the time to go into details of the rest.
