[Dev-C++] Undefined reference to IID_IDirectDraw7

[The S. <we2...@at...>]

Isn't this the correct GUID for the IDirectDraw7 interface? I've linked =
to libddraw.a and libdxguid.a. I've included windows.h, windowsx.h, and =
ddraw.h. It still doesn't work. I've browsed the message boards for =
hours, and this seems to be a common problem with Dev-C++ (or MinGW?). =
Am I stuck using DDraw4 unless I switch to MSVC++?
