typedef u32_t mem_size_t;
#else
typedef u16_t mem_size_t;
#endif /* MEM_SIZE > 64000 */   还有一个地方 . hird_partylwip-1.3.1portsstellarisincludearch/cc.h(35): error:  #40: expected an identifier
. hird_partylwip-1.3.1srcincludelwip/sys.h(45): error:  #20: identifier "u8_t" is undefined   定义 typedef unsigned    char    u8_t;   定义有错么，请赐教！ 此帖出自小平头技术问答
