Modified Files:

        src/usr.bin/xlint/lint1: tree.c

Log Message:
lint: document bug in typeok_eq

Since rt is an alias for rn->tn_type->t_tspec, it cannot be PTR and VOID
at the same time.  This makes the condition unsatisfiable.  Removing
that part of the code didn't show any change in behavior, as expected.

It may even be that fixing this obvious bug doesn't show any change in
behavior since that function is only used in a single place and
check_pointer_comparison performs its own checks before issuing any

At least the test cases added to msg_124.c all run as expected.
