+ function specifiers ("inline").
+
+ - Type specifiers (typespec_*).
+
+ - Type qualifiers (TYPE_QUAL).
+
+ - Attribute specifier lists (attributes).
+
+ These are stored as a TREE_LIST; the head of the list is the last
+ item in the specifier list. Each entry in the list has either a
+ TREE_PURPOSE that is an attribute specifier list, or a TREE_VALUE that
+ is a single other specifier or qualifier; and a TREE_CHAIN that is the
+ rest of the list. TREE_STATIC is set on the list if something other
+ than a storage class specifier or attribute has been seen; this is used
+ to warn for the obsolescent usage of storage class specifiers other than
+ at the start of the list. (Doing this properly would require function
+ specifiers to be handled separately from storage class specifiers.)
+
+ The various cases below are classified according to:
+
+ (a) Whether a storage class specifier is included or not; some
+ places in the grammar disallow storage class specifiers (_sc or _nosc).
+
+ (b) Whether a type specifier has been seen; after a type specifier,
+ a typedef name is an identifier to redeclare (_ts or _nots).
+
+ (c) Whether the list starts with an attribute; in certain places,
+ the grammar requires specifiers that don't start with an attribute
+ (_sa or _nosa).
+
+ (d) Whether the list ends with an attribute (or a specifier such that
+ any following attribute would have been parsed as part of that specifier);
+ this avoids shift-reduce conflicts in the parsing of attributes
+ (_ea or _noea).
+
+ TODO:
+
+ (i) Distinguish between function specifiers and storage class specifiers,
+ at least for the purpose of warnings about obsolescent usage.
+
+ (ii) Halve the number of productions here by eliminating the _sc/_nosc
+ distinction and instead checking where required that storage class
+ specifiers aren't present. */
