It looks like there are some prototypes missing:
> C:\DOCUME~1\hdaume\LOCALS~1\Temp\ghc920.hc:59: warning: implicit
> declaration of function `prim_rgb'
GHC might not generate correct calls to these functions unless there is
a visible prototype. In fact, taking this example, the definition of
prim_rgb is
DWORD prim_rgb(BYTE arg1,BYTE arg2,BYTE arg3)
but its FFI declaration says
foreign import ccall "prim_rgb" unsafe
prim_rgb :: Word32 -> Word32 -> Word32 -> IO (Word32)
this looks a bit strange - is there a green-card expert out there to
explain what's going on? Why have the BYTEs been turned into Word32s?
Cheers,
Simon
