I see that we already have a money_format that has been used for OS Win in /includes/current_user.inc on line 369:

// function money_format doesn't exist in OS Win.
if (!function_exists('money_format'))
{
    function money_format($format, $number) 
    {
        return price_format($number);
    } 
}    

All windows users have been using this routine for years without problems. Maybe we should include the function here suggested by @PaulSipley instead. I see that this function is listed in PHP.NET as an alternative to money_format. There is also another slightly better version we can use.

What do you think?

A proper refactoring to a supported library/function would be preferred, but this works as an interim solution.

Hope this helps
