I guess you missed it, there is a !!freeware!! C compiler that works. It is called Harvest C. I don't know where you can get the program itself, but you will need to get the Header files, those can be obtained at: ftp://pascal.zedat.fu-berlin.de/pub/mac/lang and /pub/mac/MPW I believe, and the files you need will be: CIncludes.sit.bin and Libraries.sit.bin hope this helps... steve...
