  I've been trying to create a data type that holds an int or intlike chunk
of data that is incompatible with any other types (to generate errors if
someone assumes that it's the same type as an int).. I've found that

typedef struct { int Value; } TypeA;
typedef struct { int ValueWithADifferentName; } TypeB;

  makes two compatible types; a variable of TypeA can be assigned to a
variable of TypeB without any warnings.. but

typedef struct { int Value; } TypeA;
typedef struct { unsigned Value; } TypeB;

  is incompatible, which is what I want and it works.. but what if I want
three or more incompatible types?
