- Subject: dependence.c: remove unused variable
I was playing some with lint too look for serious problems. I found mostly
minor issues (like redundant computations etc.), and I'll send patches for
these after the tree has been branced. This is one of the "serious" problems
I found (use of uninitialized variable) although it doesn't affect the
compiler. But I'd like it removed to reduce the spurious "serious" warnings.
Bootstrapped and tested on i386-unknown-netbsdelf1.5ZA.
