The C standard unfortunately.
22.214.171.124 footnote 182 & 183 says that the numeric_limits<short>::max is
equal to SHRT_MAX and numeric_limits<short>::min is equal to SHRT_MIN. The C
standard says the SHRT_MIN and SHRT_MAX should have an absolute values >=
32767. The std::numeric_limits<short>::max also has to return a value of
type short, taken together this combination of rules implies that short has
to be at least 16 bits.
