为什么程序在定义时，老出现错误？例如下别的定义：

static int panelHandle;  
static int NumChan;
static int StartChan;
static FLOAT *GainArray;
static USHORT TrigMode;
static FLOAT *VoltageArray;
static USHORT iGainCode[4];
static ULONG dwDeviceNum=0;
static LONG DiverHandle=(LONG)NULL;
static float M_fVoltage[5][8];
char project[MAX_PATHNAME_LEN];
char path[MAX_PATHNAME_LEN];
static LPT_MAIConfig lpMAIConfig;
static LPT_MAIVoltageIn lpMAIVoltage;
static LPT_DioSetPortMode lpDioSetPortMode;
static LPT_DioWriteBit lpDioWriteBit;
