The locale containing your punctuation facet needs to be imbued in
the stream passed to money_get<>::get () in order for the function
to find it. Otherwise the default moneypunct (with an empty curr_symbol)
is used.
Also, the name of the function is do_thousands_sep(). The one in your
facet is misspelled (it's missing an 's' at the end).
Finally, the program needs to #include <locale> to bring moneypunct
et al into the namespace. Other than that, it seems correct but I
can't tell you if it works with the latest libstdc++ or not. It does
produce similarly bogus output with the older version that comes with
gcc 3.0.1.
