Modified Files:
        basesrc/usr.bin/xlint/lint1: decl.c

Log Message:
Prevent lint1 from coredumping on invalid c code such as:

    foo((sockaddr *(void *))0);

This fix is imperfect, because right now we just check the subtype
chains for NULL and we return to the caller when the loop ends, leaving
the upper layers to cope with the syntax error. Ideally we should:

        a.) return an error to the upper layer, or
        b.) not call the type analysis routines in the presence of a syntax
            error.

That would require a significant re-write which would take much more time
than I have...
