Log Message:
lint: do not allow struct{const;}

In traditional C, a struct member was defined syntactically as
'type-specifier struct-declarator-list', the concept of a type-qualifier
was not known back then.

C90 invented the type-qualifier 'const' and relaxed the syntactic
requirement for struct member declarations by allowing 'const x'. Having
only a type-qualifier without an actual type may be regarded as an
"incomplete type", which would be forbidden by C90 and later.

Anyway, this doesn't occur in practice anyway, so there is no need for
lint to try to parse it.  This removes a bit of dead code, since a
type-qualifier-list can never have type struct or union.
