I understand that it is hard, so let me ask another question, if the
gettext loading support was missing, how much time would someone need to
implement it. Ballpark figure is enough (a day, a week, a month?).

Can you answer the question above?

Thats great, so it should be easy to integrate locale::format and
boost::format, shouldn't it?

Ok I'd settle for this:

boost::date_time dt = ...;
boost::locale::date_time ldt = dt;
locale::format("Today is {1,date}.") % ldt

locale::format("Today is {1,date}.") % locale::date_time(dt)

Yes, that was kind of the Idea.
