    #说明: C库函数定义头文件 
	----------------------------------  Bug  -------------------------------------- 
 
	----------------------------------  TODO list  -------------------------------------- 
 
	----------------------------------修正-------------------------------------- 
	2004-5-2	1、为调试和内核的输出，添加TRACE和printk宏定义 
				2、定义mdelay宏，毫秒级延时 
				3、添加版本号的定义MAJOR, MINOR, BUILD VERSION 
 
	2004-4-30	1、添加CONSOLE宏定义，可以定义串口输出的控制台 
				2、定义CONSOLE_PUTC宏，作为标准控制台输出宏。 
					printf 时被fputc调用 
				3、添加Uart_SendChar函数，如果发送'\n'则自动发送'\r'， 
					适合于控制台输出 
 
	2004-4-26	创建
