    Greetings,
    I have just downloaded dev-c++ win7/64bit, and started compiling the Examples.
    In the WinTest.dev program, i get an error on line# 125 :
    Test.c:125:1: error: expected initializer before 'int'
    The code around there is :

    int STDCALL

    WinMain (HINSTANCE hInst, HINSTANCE hPrev, LPSTR lpCmd, int nShow)
    {
    HWND hwndMain;/ Handle for the main window. /
    MSG msg;/ A Win32 message structure. /
    WNDCLASSEX wndclass;/ A window class structure. /
    char*szMainWndClass = "WinTestWin";
    line 125 is <>

    Anyone see an error there?
    I can Post the whole code if that helps.
    Thanks...vmars316

    The main message loop. All messages being sent to the windows
    of the application (or at least the primary thread) are retrieved
    by the GetMessage call, then translated (mainly for keyboard
    messages) and dispatched to the appropriate window procedure.
    This is the simplest kind of message loop. More complex loops
    are required for idle processing or handling modeless dialog
    boxes. When one of the windows calls PostQuitMessage GetMessage
    will return zero and the wParam of the message will be filled
    with the argument to PostQuitMessage. The loop will end and
    the application will close.
    /
    while (GetMessage (&msg, NULL, 0, 0))

    TranslateMessage (&msg);
    DispatchMessage (&msg);

    Oops,
    I must have tweaked something accidentally,
    cause it is working fine now.
    Thanks...vm
