Log:
 The integral type with which an enumerated type is equivalent is,
 according to the ANSI C standard, implementation-defined; it could be
 unsigned, in which case checking whether it's < 0 will cause a compiler
 warning.
 
 Casting a signed enum to unsigned will turn negative values into Really
 Big Positive Values, so casting to unsigned and comparing against the
 maximum value will catch values with the sign bit set regardless of
 whether enums are signed or unsigned.
