[PATCH 0/2] Fix issues found by gcc 4.6.0

In general, our sources are quite clean. However, a few variables were unused. Previous gcc version did not find them because they were assigned values, but those values were never used nontheless.

The tricky question is whether 2/2 really fixes an issue or not. Unfortunately, my time is too limited to go into detail, but I figured it'd be better to raise the issue than to remain silent.

  Remove unused variables
  Actually use retval
