following guarantees are provided concerning a Haskell type @CT@
representing a C type @t@:
-* If a C function prototype has @t@ as an argument or result type,
- the use of @CT@ in the corresponding position in a foreign declaration
- permits the Haskell program to access the full range of values encoded by
- the C type; and conversely, any Haskell value for @CT@ has a valid

representation in C.
-* @'sizeOf' ('undefined' :: CT)@ will yield the same value as

@sizeof (t)@ in C.

+* @'alignment' ('Prelude.undefined' :: CT)@ matches the alignment
+ constraint enforced by the C implementation for @t@.
-* The members 'peek' and 'poke' of the 'Storable' class map all values of
- @CT@ to the corresponding value of @t@ and vice versa.

+* When an instance of 'Prelude.Bounded' is defined for @CT@, the values
+ of 'Prelude.minBound' and 'Prelude.maxBound' coincide with @t_MIN@
