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.

Umm, minor nit: bit fields were added to/as of 'Typesetter C', which I
gather was intermediate between V6 and V7.
