Actually one famous mistake is already known with 64 bit machines.
8-bit char, 16-bit short, 32-bit int, 64-bit long is technically valid
but it is weird for int to have a different size from both short and long.

Another mistake was already known at the time of K&R-1, when there was
only one size for char but one of their cited implementations was on a
machine which had two sizes for char (either 6 or 9 bits).

Another mistake has been known for a couple of decades, making char the
unit size for most C operations when characters actually require 16 or
32 bits (or varying numbers of bits in some encoding schemes) while the
most popular unit size is 8 bits.
