Running this on my linux machine I get exactly the output I expected,
all success:

However, when running on my OS X machine with the stock g++ (running
on 10.5.1) I get the following:

It seems that the system is only able to create C++ locales for "C"
and "POSIX", which is puzzling, and also very unsatisfactory.
It would be unhappy, but at least settling, if I found a page that
said something like "C++ locales on OS X only support "C" and "POSIX",
tough luck!". However, such a page is nowhere to be found, and in fact
I have found evidence to the contrary.
Searching "site:apple.com std::locale" in google brings up various
pages where people describe issues with the usage of std::locale.
However, these pages pertain to issues with the usage of the locale
after it has already been created, which implies that the people who
made the posts were actually able to create the locale to begin with;
so why am I not able to create them?
I've been banging my head against the wall for a while now; any help
would be much appreciated
