I've looked into exif-utils.h and did small changes to:

typedef char            ExifByte;          /* 1 byte  */
typedef char *          ExifAscii;
typedef uint16_t        ExifShort;         /* 2 bytes */
typedef uint32_t        ExifLong;          /* 4 bytes */
typedef struct {ExifLong numerator; ExifLong denominator;} ExifRational;
typedef char            ExifUndefined;     /* 1 byte  */
typedef int32_t         ExifSLong;         /* 4 bytes */
typedef struct {ExifSLong numerator; ExifSLong denominator;} ExifSRational;


Now, all problems should disappear. Only some printf-Statements, which need
format modifier for eg ExifLong, are throwing warnings. Are there any
specifier for uint32_t which can be used with printf and friends?
