The TI C3x DSP uses a 32-bit int as a char; the machine can only address
32-bit words. The Cray XMP/YMP is also a word addressable system, but
the "C" implementation used a 8-bit quantity for a char and did the
manipulation in software. I'm assuming both are "correct" as far as the
standard went at the time and that the size of a char was left to the
