Actually what that means is that it is two bytes where a byte is defined by
BITS_PER_UNIT. While in most targets that makes it 16-bits, HImode is not
always 16-bits. See the c4x and dsp16xx ports which have 64-bit and 32-bit
HImodes respectively.

(But don't let that confuse the issue for a new port if you have a "normal"
byte.)
