Follow-up Comment #2:


> gettext still uses gethostbyname, which is considered generally deprecated
function in favor of getaddrinfo.
> It would be good to replace the usage in gettext to future-proof it.

Thanks for the report. Done through
https://git.savannah.gnu.org/gitweb/?p=gettext.git;a=commitdiff;h=c5cdf41d436261b279c172753ac727335d44b9fd

Correct. And user-email is used by msginit.

> Perhaps a workaround could be to drop (remove) the hostname program from
gettext on Linux systems, etc?

It is true that on some Linux systems, gettext's 'hostname' program implements
a subset of the functionality of the (Debian-maintained) 'hostname' program.
The reason why it exists in gettext is for portability to systems that don't
have it. msginit should work also on those systems.

Do all Linux distros ship with the 'hostname' program by default? I wouldn't
bet on it.
