Paul had a preference for "Posix" Paul?
I have seen "POSIX" far more than any other spelling. "Posix" just looks wrong to me. Maybe in 20 years it'll look right, the way "Fortran" does now ... As far as Texinfo goes, I recommend just writing it as-is with no markup. I see no significant benefit to either @acronym or @sc that outweighs the simplicity. (Ditto for "GNU", etc.) karl
