I agree, with two notes:
- I would add "codes returned by other systems we consider major enough
to care about", specifically including OSes we support compatability
modes for (in particular, I've far too often seen vendor OSes return
undocumented error codes);
- It should be possible to tell from reading the manpage what subset of
these classes each errno falls into. I don't go as far in this
direction as I suspect Greg Woods does; I don't (for example) want
to see this-implementation errnos broken out into a list distinct
from any of the others. But it would be a Good Thing to have.
