I've just compiled the first 10 linux downloaded lessons, every lesson has had a compiling error that requires an additional header: #include <stdinc.h> for it to compile correctly, I'd be happy to add these to all the lessons and re-tar.gz them, unless someone else has immediate access to them, but I'd like to seem them brought up to day from the last date they were checked, which is currently showing 1999. :eek:

stdinc.h is no default header.
Are you sure what you are missing isn't something like stdio.h or stdlib.h (or both?).
