Very good read for anyone that wants to write this outdated language in 2016.

char is CHAR_BIT, C standard requires it to be at least 8 bit; POSIX mandates CHAR_BIT == 8

Many Texas Instruments DSPs have 16 or 32 bit chars; machines with 36 bit architectures, e.g. DEC PDP-6/10, could have 5, 6, 7, 8 or 9 bits per character (+ 4, 0, 1, 4 or 0 spare bits) and due to C standard requirement of at least 8 bits per char, they implemented 9 bit chars.
