/* This file can be parametrized with the following macros:
     VASNPRINTF         The name of the function being defined.
     FCHAR_T            The element type of the format string.
     DCHAR_T            The element type of the destination (result) string.
     FCHAR_T_ONLY_ASCII Set to 1 to enable verification that all characters
                        in the format string are ASCII. MUST be set if
                        FCHAR_T and DCHAR_T are not the same type.
     DIRECTIVE          Structure denoting a format directive.
                        Depends on FCHAR_T.
     DIRECTIVES         Structure denoting the set of format directives of a
                        format string.  Depends on FCHAR_T.
     PRINTF_PARSE       Function that parses a format string.
                        Depends on FCHAR_T.
     DCHAR_CPY          memcpy like function for DCHAR_T[] arrays.
     DCHAR_SET          memset like function for DCHAR_T[] arrays.
     DCHAR_MBSNLEN      mbsnlen like function for DCHAR_T[] arrays.
     SNPRINTF           The system's snprintf (or similar) function.
                        This may be either snprintf or swprintf.
     TCHAR_T            The element type of the argument and result string
                        of the said SNPRINTF function.  This may be either
                        char or wchar_t.  The code exploits that
                        sizeof (TCHAR_T) | sizeof (DCHAR_T) and
                        alignof (TCHAR_T) <= alignof (DCHAR_T).
     DCHAR_IS_TCHAR     Set to 1 if DCHAR_T and TCHAR_T are the same type.
     DCHAR_CONV_FROM_ENCODING A function to convert from char[] to DCHAR[].
     DCHAR_IS_UINT8_T   Set to 1 if DCHAR_T is uint8_t.
     DCHAR_IS_UINT16_T  Set to 1 if DCHAR_T is uint16_t.
     DCHAR_IS_UINT32_T  Set to 1 if DCHAR_T is uint32_t.  */

               {Since always u = (q* * [b[i-1],...,b[0]] div beta^i) + 1
                               < q* + 1 <= beta,
                the carry u does not overflow.}
