你是不是该把错误提出来？

我刚接触API,这是一本老书上的例子,我原原本本照打出来,编译时有错,却不知道怎么错了,还望赐教

错识有五个正确代码如下：
#define STRICT
#include<windows.h>
#include<windowsx.h>
#include<string.h>
char Name[]="MakeWin";
LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);
int pascal WinMain(HINSTANCE hInst,HINSTANCE hPrevInstance,LPSTR lpszCmdParam,int nCmdShow)
{
    HWND hwnd;
    MSG Msg;
    WNDCLASS W;
    memset(&W,0,sizeof(WNDCLASS));
    W.style=CS_HREDRAW|CS_VREDRAW; //1
    W.lpfnWndProc=WndProc;
    W.hInstance=hInst;
    W.hbrBackground=GetStockBrush(WHITE_BRUSH);
    W.lpszClassName=Name;
    RegisterClass(&W);
    hwnd=CreateWindow(Name,Name,WS_OVERLAPPEDWINDOW,10,10,600,400,NULL,NULL,hInst,NULL);//2
    ShowWindow(hwnd,nCmdShow);
    UpdateWindow(hwnd);
    while(GetMessage(&Msg,NULL,0,0))
    {
        TranslateMessage(&Msg);
        DispatchMessage(&Msg);
    }
    return Msg.wParam;
}

LRESULT CALLBACK WndProc(HWND hwnd,UINT Message,WPARAM wParam,LPARAM lParam) //4
{
    if(Message==WM_DESTROY)
    {
        PostQuitMessage(0);
        return 0;
    }
    return DefWindowProc(hwnd,Message,wParam,lParam);//5
}
