In the end, thinking about it twice I merged version which always prints TERRNO,
because we don't have any special explanation for TCONF, therefore the only
explanation is the errno itself:

(errno == EOPNOTSUPP ? TCONF : TBROK) | TERRNO,

Merged, with your Reviewed-by: and Co-developed-by:. Thanks!

Kind regards,
Petr
