    Log a warning in gnc_get_locale() instead of writing to stderr.

commit 67f5dfb03499b5b57943ac68f684931594ecc0e0

    Bug 796946 - Mortgage and Loan Repayment Setup tool crashes when...
    
    exiting "Loan Repayment Options" page.
    
    Because libstdc++ on Windows doesn't support any C++ locales besides
    "C" and throws an exception if you try.
    
    To work around this use GetNumberFormatW (not GetCurrencyFormatW,
    that includes the currency symbol) to create a formatted number string
    with the right separators, grouping, and precision.
