说得很明白了啊 missing function header
这个错误通常是因为函数的函数头后边加了分号引起

int WINAPI WinMain(
HINSTANCE hInstance, // handle to current instance
HINSTANCE hPrevInstance, // handle to previous instance
LPSTR lpCmdLine, // pointer to command line
int nCmdShow // show state of window
); <-------去掉这个分号
{
WNDCLASS wndcls; //设计一个窗口类
wndcls.style=CS_HREDRAW|CS_VREDRAW;
wndcls.lpfnWndProc=Winsunproc;
wndcls.cbClsExtra=0;
