Hi
I was trying to add a primitive function for which I modified Prelude.hs, Prelude.c and Primitive.hs. I rebuilt the prelude using 'yhc -c - redefine -prelude' and then did an scons, but I got the following error:
Recently the flag format changed, you must use two --'s for long options
yhc -c --redefine --prelude Actually, my version is a couple months old, and it builds with a single '-'. I tried with --, and everything is as before: the Prelude builds, but the main scons fails with the below error. How do I resolve that? Thanks.

I undid all the changes I made, and I still get this error. I did not change anything related to Integral or Integer AFAIK and I didn't even open the Word.hs file, and the Prelude still has the instance declaration (instance Integral Integer where...).
How do I resolve this error? I don't want to do an scons fullclean because I'm working on a modified version of yhc. I haven't come across this error before that I remember, and I was able to build and pass the unit tests with no problem till this happened. Thanks for your help.
