--- DESCRIPTION ---------------------------------------------------------------
--
-- Abstract syntax of C header files.
--
--- DOCU ----------------------------------------------------------------------
--
-- language: Haskell 98
--
-- The tree structure corresponds to the grammar in Appendix A of K&R. This
-- abstract syntax simplifies the concrete syntax by merging similar concrete
-- constructs into a single type of abstract tree structure: declarations are
-- merged with structure declarations, parameter declarations and type names,
-- and declarators are merged with abstract declarators.
--
-- With K&R we refer to ``The C Programming Language'', second edition, Brain
-- W. Kernighan and Dennis M. Ritchie, Prentice Hall, 1988. This module
-- supports the C99 `restrict' extension
-- <http://www.lysator.liu.se/c/restrict.html>, `inline' functions, and also
-- the GNU C `alignof' extension.

-- - at most one storage class specifier is allowed per declaration;

-- the elements of K&R's init-declarator-list are represented by triples
-- of the form `(Just declr, oinit, Nothing)', where `oinit' maybe
-- `Nothing' or `Just init'; and
-- - abstract declarators are not allowed.
--
-- * Structure declarations (K&R A8.3):
--
-- - do not allow storage specifiers;
-- - do not allow initializers;
-- - require a non-empty declarator-triple list, where abstract declarators
-- are not allowed; and
-- - each of the declarator-triples has to contain either a declarator or a
-- size expression, or both, ie, it has the form `(Just decl, Nothing,
-- Nothing)', `(Nothing, Nothing, Just size)', or `(Just decl, Nothing,
-- Just size)'.
--
-- * Parameter declarations (K&R A8.6.3):
--
-- - allow neither initializers nor size expressions;
-- - allow at most one declarator triple of the form `(Just declr, Nothing,
-- Nothing)' (in case of an empty declarator, the list must be empty); and
-- - allow abstract declarators.
--
-- * Type names (A8.8):
--
-- - do not allow storage specifiers;
-- - allow neither initializers nor size expressions; and
-- - allow at most one declarator triple of the form `(Just declr, Nothing,
-- Nothing)' (in case of an empty declarator, the list must be empty),
-- where the declarator must be abstract, ie, must not contain a declared
-- identifier.
