+\begin{describe}{gf}{c-qualifier-keyword @<qualifier> @> @<string>}
+ Return, as a string, the C keyword corresponding to the Lisp @<qualifier>.
+
+ There is a standard method, which deals with many qualifiers. Additional
+ methods exist for qualifier keywords which need special handling, such as
+ @|:atomic|; they are not listed here explicitly.
+
+ \begin{describe}{meth}{keyword}
+ {c-qualifier-keyword @<keyword> @> @<string>}
+ Returns the @<keyword>'s print-name, in lower case. This is sufficient

+\begin{describe}{fun}{c-type-qualifier-keywords @<c-type> @> @<list>}

+\subsection{Storage specifiers} \label{sec:clang.ctypes.specs}
+
+Some declaration specifiers, mostly to do with how to store the specific
+object in question, are determinedly `top level', and, unlike qualifiers,
+don't stay attached to the base type when acted on by declarator operators.
+Sod calls these `storage specifiers', though no such category exists in the C
+standard. They have their own protocol, which is similar in many ways to
+that of C types.
+
+Every Lisp keyword is potentially a storage specifier, which simply maps to
+its lower-case print name in C; but other storage specifiers may be more
+complicated objects.
+
+\begin{describe}{cls}
+ {c-storage-specifiers-type (c-type) \&key :subtype :specifiers}
+ A type which carries storage specifiers. The @<subtype> is the actual
+ type, and may be any C type; the @<specifiers> are a list of
+ storage-specifier objects.
+
+ The type specifier @|(specs @<subtype> @<specifier>^*)| wraps the
+ @<subtype> in a @|c-storage-specifiers-type|, carrying the @<specifier>s,
+ which are a list of storage specifiers in S-expression notation.
+\end{describe}
+
+\begin{describe}{fun}{c-type-specifiers @<type> @> @<list>}
+ Returns the list of type specifiers attached to the @<type> object, which
+ must be a @|c-storage-specifiers-type|.
+\end{describe}
+
+\begin{describe}{mac}
+ {define-c-storage-specifier-syntax @<name> @<lambda-list> \\ \ind
+ @[[ @<declaration>^* @! @<doc-string> @]] \\
+ @<form>^* \-
+ \nlret @<name>}
+
+ Defines the symbol @<name> as a new storage-specifier operator. When a
+ list of the form @|(@<name> @<argument>^*)| is used as a storage specifier,
+ the @<argument>s are bound to fresh variables according to the
+ @<lambda-list> (a destructuring lambda-list) and the @<form>s evaluated in
+ order in the resulting lexical environment as an implicit @<progn>. The
+ value should be a Lisp form which will evaluate to the storage-specifier
+ object described by the arguments.
+
+ The @<form>s may call @|expand-c-storage-specifier| in order to recursively
+ expand storage specifiers among its arguments.
+\end{describe}
+
+\begin{describe}{gf}{expand-c-storage-specifier @<spec> @> @<form>}
+ Returns the Lisp form that @<spec> expands to within @|(c-type (specs
+ @<subtype> @<spec>))|.
+
+ If @<spec> is a list, then \descref{gf}{expand-c-storage-specifier-form} is
+ invoked.
+\end{describe}
+
+\begin{describe}{gf}{expand-c-storage-specifier-form @<spec> @> @<form>}
+ Returns the Lisp form that @|(@<head> . @<tail>)| expands to within
+ @|(c-type (specs @<subtype> (@<head> . @<tail>)))|.

+\begin{describe}{fun}{wrap-c-type @<func> @<base-type> @> @<c-type>}
+ Apply @<func> to the underlying C type of @<base-type> to create a new
+ `wrapped' type, and attach the storage specifiers of @<base-type> to the
+ wrapped type.
+
+ If @<base-type> is \emph{not} a @|c-storage-specifiers-type|, then return
+ @|(funcall @<func> @<base-type>)|. Otherwise, return a new
+ @|c-storage-specifiers-type|, with the same specifiers, but whose subtype
+ is the result of applying @<func> to the subtype of the original
+ @<base-type>.
+\end{describe}
+
+\begin{describe}{cls}{alignas-storage-specifier () \&key :alignment}
+ The class of @|_Alignas| storage specifiers; an instance denotes the
+ specifier @|_Alignas(@<alignment>)|. The @<alignment> parameter may be any
+ printable object, but is usually a string or C fragment.
+
+ The storage specifier form @|(alignas @<alignment>)| returns a storage
+ specifier @|_Alignas(@<alignment>)|, where @<alignment> is evaluated.
