			        platform_def.h	操作系统相关定义 zl 2002.11.5

	        本文件定义所有和操作系统平台相关的常量、类型、宏及头文件引用
-----------------------------------------------------------------------------*/


/*-----------------------------------------------------------------------------

条件编译常量定义约定：

(1) Windows操作系统:    OS_WINDOWS

(2) Unix(统称)操作系统: OS_UNIX
(3) Linux操作系统:      _OS_UNIX_LINUX_
(4) True64操作系统:     _OS_UNIX_TRUR64_
(5) Solaris操作系统:    _OS_UNIX_SOLARIS_

(6) 64位操作系统:       _OS_64BIT_

(7) Windows字节顺序:    _OS_WINDOWS_BYTEORDER_
(8) Solaris字节顺序:    _OS_SOLARIS_BYTEORDER_

[说明]：

a. 64位操作系统主要有：DEC True64, solaris(有时可能是32位系统,可以通过测试sizeof
   (long)是否=8来判断)

b. windows, linux, true64 等操作系统的字节顺序和solaris相反,因此分别以Windows
   和solaris为代表定义不同的字节顺序

c. Unix操作系统种类繁多，每个变种有一定的差别，因此为常见的unix系统每种定义一个
   条件编译常量
