It depends on definition of the word C.
The requirement for CHAR_BIT > 7 was not present in K&R C. IIRC, it
first came in C90.

Also, what prevents C90 compiler from using 36-bit char on Univac 1108
and 60-bit bytes on CDC 7600? Methinks, it would be very reasonable.
By chance, that* was a choice made both by TI and by Analog for C
compilers of their word-addressable DSPs.


* - not specifically 36 or 60 bits, but CHAR_BIT = native word width.
