I doubt very much that the bulk of the text was written in (or near) 2005. Thus it tells very little of the state of C in 2005, but might otherwise prove to be mildly interesting read on the 80s.

Edit: something's not right there. That's way too early. According to https://www.cs.princeton.edu/~bwk/bwkbib.html, it's 1988 and from BYTE.
