    @brief Enumeration for error code of the m17n library.

    Enumeration for error code of the m17n library.

    When a library function is called with an invalid argument, it
    sets the external variable #merror_code to one of these values.
    All the error codes are positive integers.

    When a memory allocation error happens, the function pointed to by
    the external variable #m17n_memory_full_handler is called with one
    of these values as an argument.  */

    ライブラリの関数が妥当でない引数とともに呼ばれた場合には、変数 
    #merror_code をこれらの値のどれかにセットする。すべてのエラーコード
    は正の整数である。

    メモリ割当てエラーの際には、外部変数 #m17n_memory_full_handler の指
    す関数が、これらの値のうちのどれかを引数として呼ばれる。
