Re: parse error

        in the line 110 column 11, there is a declaration of addr_t variable.
        do splint not reconize system types.
        
addr_t is not a built in language type.
It is just another typedef, as if you had written
    typedef char *addr_t;               /* Classic */
or
    typedef void *addr_t;               /* C89 */
Splint will recognise it just like it recognises any other typedef name,
that is, IF it has been correctly declared.

Look a little wider.  What other tokens are nearby?
