 * @brief  Basic common definitions
 *
 * This is a common header that should be included in all the Julius related
 * sources.  This file contains include list of basic C headers, definition of
 * common static values and function macro, and basic typedefs to handle
 * speech input and words.
 *
 * The unix function macro definition for Win32 environment is also included.
 *
 * Only the important part is documented.  Fof all the definition, see
 * the source.

 * @brief  基本の共通定義
 *
 * このファイルはすべてのライブラリで include されるべき共通ヘッダです．
 * 基本的なCヘッダファイルの include, よく使われる定数値と式マクロの定義，
 * すべての関数で共通して用いられる基本的な型の定義が含まれます．
 *
 * また，Win32 モードでのコンパイルのための関数のマクロ定義も含みます．
