>Description:
The cdecl program declares that having storage-class and
a type-qualifier is a syntax error, for example:
	cdecl> explain static const int jsb
	syntax error

Any combination of storage-class (auto, extern, register, static)
and type-qualifier (const, volatile, noalias) gives this result.

Interestingly, the reverse works fine:

	cdecl> declare jsb as static const int
	static const int jsb

BTW, the manpage also contains an error:

	<storage> ::= auto | extern | register | auto
should be:
	<storage> ::= auto | extern | register | static

>How-To-Repeat:
	This should be intuitively obvious to even the most casual observer.
