Yep. Im pretty sure I remember void being in
typesetter C also. IIRC the differences between that version of Dennis’s compiler and
what was included in 7th Edition was mostly in the libraries ie stdio was first released
as part of the typesetter compiler but it was still a work in progress.
My biggest recollection was the beginning of flipping =+ to += (It supported both but
warned you about the former), and fixing the structure elements to not be global.
Lots of odd quirks in the kernel due to early C limitations. PS->integ always has a
fond part of my memory.
