Yep, that remains correct. Same for ERR_EXIT.

Most(/All?) of the patches address cases where the implementation wasn't following the specification.

The patch about the always statement makes it behave like compound statements. Since the always statement isn't part of POSIX, this could be seen either as a bug fix or a spec change (but rather of the always statement than of ERR_EXIT).

Will that doc remain correct with respect to what it says about
ERR_EXIT after recent patches are considered?

(Still on my TODO list, have been busier than I expected so far this week.)
