Yep. Just checked that. In fact, "debut.arc" was renamed "structs.arc". Just change this in "arc2c.arc", and it will be working.
1. Yes, I will probably. I only work with the Anarki version, so when I'm finding something useful in the source, I don't even know if it's "official" or not.
2. Yes. Using Anarki as a repository for the stable versions of arc2c seems a good idea.
Also, another question - Anarki has a CONVENTIONS file, will we be following this too? One Anarki convention that isn't followed is with regards to tabs and indentation, is it OK to change the tabs to follow Anarki conventions or do you prefer the current indentation?
Oh, sure, I never really checked the CONVENTIONS file, but I think it's better to indent this way (it's the tradition after all:). I usually don't do it naturally because it's not the way I learnt it, but I guess I should follow the conventions anyway. So, OK, let's change the tabs.
If you have macports (and you should!) you can do this:
$ macports install mzscheme
That'll get mzscheme running. Then I downloaded the latest anarki from github (http://github.com/nex3/arc/tarball/master) I untarred it and renamed it to "arc". Then I went back to my shell.
