Thereby pre-empting a design decision that is duly Cygwin's. Again:
"Do NOT call Windows functions in Cygwin libraries, unless the lib is
doing something very special which isn't provided by POSIX functions.
Only call POSIX functions. Don't mix the Cygwin and the
Windows environment. Please leave the interfacing to the underlying
OS the sole job of Cygwin."
Besides, your proposal wouldn't work, due to the LANG=C.UTF-8 setting
in /etc/profile.d/lang.sh. And if lang.sh was changed to pick up the
Windows setting, libintl wouldn't need to muck about with Windows

"Libintl is a library that provides native language support to
programs." It doesn that perfectly well without going against the
wishes of the platform maintainers. Users can choose a language by
setting LANG or LC_*, as documented in the Cygwin manual. In the
probably-soon-to-be-default "Cygwin Terminal", they can even choose
the locale in the options dialog.

That's certainly a valid opinion. Please take it to cygwin-developers
and try to convince Corinna to change that decision.

True. Nevertheless there'll be complaints, and I can't remember any
demands for this. Then again, complaints would be easy enough to deal

Maybe, but that's not Cygwin's problem to solve.

They do indeed usually default to the local language. This prompts
questions like these from some users:

And that's not a helpful statement.
