Oops, sorry I copied the wrong line in my e-mail. I'm using stdcall in the
foreign import. I first tried with ccall and then realized the header was
defining the stdcall convention when built on windows. The link error occurs
when I use stdcall. When I use ccall it links but gives segmentation faults
when I run the program.

Here is the last import I used.
foreign import stdcall unsafe "sapnwrfc.h RfcUTF8ToSAPUC"
  f_RfcUTF8ToSAPUC :: RfcBytePtr -> CUInt -> SapUCPtr -> Ptr CUInt -> Ptr
CUInt -> RfcErrorInfoPtr -> IO RfcRetCodeType
