[1] 'GET_DATA_FOUR_BYTES' define and 'SET_DATA_FOUR_BYTES' define?
[2]
#define  GET_DATA_BIT(pdata, n) \
    ((*((pdata) + ((n) >> 5)) >> (31 - ((n) & 31))) & 1)

#define  GET_DATA_BIT_CHANGED(pdata, n) \
    ((*((unsigned char *)(pdata) + ((n) >> 5)) >> (31 - ((n) & 31))) & 1)

GET_DATA_BIT under vs2010 will got error C2296,C2036,C2100.

#define  GET_DATA_BIT_CHANGED_2(pdata, n) \
    ((*((l_uint32 *)(pdata) + ((n) >> 5)) >> (31 - ((n) & 31))) & 1)

I don't know which is correct.

I don't understand your problem.  The image data ptr must be cast to an 
unsigned 32 bit int, as in arrayaccess.h.  Why are you using these other macros?
