Very nice.

Waiting on a value to be assigned for it...
This one's really a pain since the O_* constants are per-arch.

Ugly mess I'm not looking forward to.

My feeling is that dbm stuff will stay in an external third-party
library.

Also waiting on a decision for the value; glibc folks are
non-responsive.

Seem to be errors in POSIX.

All optonal.

Fixed, I hope.

Still need to look at these.

Unfortunately glibc also defines it as a pointer type (void *).

I think glibc is also missing these, at least in the old version I'm
looking at. We'll need to get agreed-upon values. Hopefully a newer
glibc has them for me to pull..
