Aaaah that oen . . . I got DirectDraw4_iid by going to
ddraw.h in the Dx9 SDK.  I saw a DEFINE_GUID for
IID_IDirectDraw4, and I figured that was the IID.  I
cut-and-paste, converting the list of integers into a
string, and I formatted the string like other GUID's I
was seeing in Euphoria.  Unfortunately, I goofed: I
left a ", 0x05".  Even when I fixed it, however, it
didn't work.

It worked!  I removed the add_iid call completely and
called "SetCooperativeLevel" with no problem.
