Well, I cannot.  It seems that libc locale support is broken in Red Hat 
8.0, so all the messages are in English.  I'll try to fix all this mess as 
soon as possible :-(

I think that "POPT_" should be replaced with "_".  There are already many
local changes to popt.  If we decide to update popt at a later date, then
we can think if it's OK to obsolete gettext 0.10.x.
