[Yhc] Unknown preprocessor directive

Hi all, Work on getting YHC to compile under Windows is progressing well. Can someone suggest a reason why I get the following error when trying to build the YHC library? inst\bin\yhc.exe -i src/packages/yhc-base-1.0/ -d src/packages/yhc-base-1.0/ -c src\packages\yhc-base-1.0\Foreign\Word.hs yhc.exe: Unknown preprocessor directive at line 16 in file "D:\\programming\\yhc-devel/src\\packages\\yhc-base-1.0\\Foreign\\Word.hs" define WORD_TYPE(T,BS,LB,UB) \ Cheers, Andrew
