Here are a couple of possible reasons:
 
K&R2: "Fields behave like small, unsigned integers, and may
participate in arithmetic expressions just like other integers."
 
K&R2: "A field may not overlap an int boundary..."
 
K&R2: "... they may be stored only in int's (or, equivalently,
unsigned's ..."
 
How would you declare a bitfield wider than the widest
available int?
