STM32在MDK中int占的位数跟KEIL C51不一样吗？

摘抄的stdint.h里面的：

/* exact-width signed integer types */
typedef   signed          char int8_t;
typedef   signed short     int int16_t;
typedef   signed           int int32_t;
typedef   signed       __int64 int64_t;

/* exact-width unsigned integer types */
typedef unsigned          char uint8_t;
typedef unsigned short     int uint16_t;
typedef unsigned           int uint32_t;
typedef unsigned       __int64 uint64_t;

记得51编程的时候 int型的是占16位，2个字节啊，int = short int 吧？
今天看STM32这个stdint.h里面貌似是int = long int ,占了4字节，32位呀？有点糊涂了，MDK和KEIL C51这边的默认设置有区别吗？
