- Actually, on further thought, I don't think it is legal. In the statement:
-
- A const* a3 ;
-
- The const is part of the `declaration-specifiers', and not the
- `declarator'. When multiple symbols are declared in the same line, as
- here, the list contains declarators, and cannot contain additional parts
- of the declaration-specifiers.
-
- A quick check of the grammar shows that the first token of a declarator
- must be one of { `*', `(' , <identifier> }. The keyword `const' is none
- of these.
