我的devcpp版本是5.8.3 我的程序：

#include <stdio.h>
int main()
{
    unsigned short int a;
    signed short int b;
 
    a = 5;
    b = 5;
 
    printf("a = %d  b = %d", a, b);
 
    return 0;
}

devcpp报错：

178 85 c:\program files (x86)\dev-cpp\mingw64\x86_64-w64-mingw32\include\stdio.h [Error] unknown type name '_locale_t'

我的程序错哪了？？
