Ok, a bit unfortunate, but oh well, I'm not going to worry about it.

I guess I'm a bit confused at to what that means.  The man page says that
"denotes native environment", but it doens't explain how that's different
from the "C" locale, which it says is the standard locale for c programs.
Or, does that mean that calling setlocale with "" causes it to look up the
actual environment variables and set the locale based on that?  (which doesn't
sound exactly like the "native" environment, it's the settings that the
current user overrode the defaults with.)
