Yes, you're right. The localeconv() API gives information from which
nl_langinfo (CRNCYSTR) could be fixed.

But what's the point in doing that?
  - Anyone doing serious monetary formatting will use localeconv(),
    since it provides more detailed information than nl_langinfo (CRNCYSTR),
    or use strfmon() right away.
  - Anyone doing serious monetary formatting in a French locale will not
    use NetBSD, since it's "local currency symbol" is "Eu", even in the
    ISO-8859-15 locale - a value that is not seen in real life.

So I think that just documenting the problem is enough.
