一个VC++编译错误
大家好，我在编译文件时，出现了这样的错误，可是凭我的VC知识，我看不出有什么错误，大家帮我看看吧，谢谢！源程序为：
struct BACnet_Application_Data_Value;
typedef struct BACnet_Application_Data_Value {
bool context_specific; /* true if context specific data */
uint8_t context_tag; /* only used for context specific data */
uint8_t tag; /* application tag data type */
union {
/* NULL - not needed as it is encoded in the tag alone */
#if defined (BACAPP_BOOLEAN)
bool Boolean;
#endif
#if defined (BACAPP_UNSIGNED)
uint32_t Unsigned_Int;
#endif
#if defined (BACAPP_SIGNED)
int32_t Signed_Int;
#endif
#if defined (BACAPP_REAL)
float Real;
#endif
#if defined (BACAPP_DOUBLE)
double Double;
#endif
#if defined (BACAPP_OCTET_STRING)
BACNET_OCTET_STRING Octet_String;
#endif
#if defined (BACAPP_CHARACTER_STRING)
BACNET_CHARACTER_STRING Character_String;
#endif
#if defined (BACAPP_BIT_STRING)
BACNET_BIT_STRING Bit_String;
#endif
#if defined (BACAPP_ENUMERATED)
int Enumerated;
#endif
#if defined (BACAPP_DATE)
BACNET_DATE Date;
#endif
#if defined (BACAPP_TIME)
BACNET_TIME Time;
#endif
#if defined (BACAPP_OBJECT_ID)
BACNET_OBJECT_ID Object_Id;
#endif
} type;
/* simple linked list if needed */
struct BACnet_Application_Data_Value *next;
} BACNET_APPLICATION_DATA_VALUE;
错误信息为：
d:\net\bacnet-stack-0.4.1\bacnet-stack-0.4.1\include\bacapp.h(87) : error C2059: syntax error : '}'
d:\net\bacnet-stack-0.4.1\bacnet-stack-0.4.1\include\bacapp.h(90) : error C2059: syntax error : '}'
