JP, it's a problem to pull a dependency on wxwidgets 2.9.x? and use the  CDouble methods from
wxString? ,

It seems to work here, and LOCALE_IO seems dangerous regarding threading.

This is the FromCDouble implementation, they used a Replace, as my original solution :-)

wxString wxString::FromCDouble(double val, int precision)
{
    wxCHECK_MSG( precision >= -1, wxString(), "Invalid negative precision" );

#if wxUSE_STD_IOSTREAM && wxUSE_STD_STRING
    // We assume that we can use the ostream and not wstream for numbers.
    wxSTD ostringstream os;
    if ( precision != -1 )
    {
        os.precision(precision);
        os.setf(std::ios::fixed, std::ios::floatfield);
    }

    os << val;
    return os.str();
#else // !wxUSE_STD_IOSTREAM
    // Can't use iostream locale support, fall back to the manual method
    // instead.
    wxString s = FromDouble(val, precision);
#if wxUSE_INTL
    wxString sep = wxLocale::GetInfo(wxLOCALE_DECIMAL_POINT,
                                     wxLOCALE_CAT_NUMBER);
#else // !wxUSE_INTL
    // As above, this is the most common alternative value. Notice that here it
    // doesn't matter if we guess wrongly and the current separator is already
    // ".": we'll just waste a call to Replace() in this case.
    wxString sep(",");
#endif // wxUSE_INTL/!wxUSE_INTL

    s.Replace(sep, ".");
    return s;
#endif // wxUSE_STD_IOSTREAM/!wxUSE_STD_IOSTREAM
}
