LC_COLLATE and LC_CTYPE are independent settings. But in any case
Tatsuo is correct about the long-term direction we need to take ---
in order to come anywhere near SQL-standard behavior, we have to support
multiple locales simultaneously, and that means that the standard C
library's API isn't gonna do it.

I noticed by chance that glibc has a "reentrant locale" API that seems
to allow for efficient access to multiple locales concurrently. Perhaps
it would be a reasonable solution to support multiple locales only on
machines that have this library. If we have to write our own locale
support it's likely to be a long time coming :-(
