If you mean that you're using the latest from CVS, something is wrong with your PATH because winewrap has been removed for a few days now. I also means that you're using an old winegcc/wineg++. What I suggest you do is that first you remove these old binaries. Try:
which wine{gcc,g++,cpp,wrap}
to figure out what exactly you are running (and what you need to delete).
I don't have any old binaries. I just reformatted by entire system - this is the first time my system has had Wine installed.
I'm using snapshot wine-20040213.
