The build error was reported at the Gentoo Bugzilla [1].

When compiling with gcc-4.6.0, a build error occurs: 
"variable ‘old’ set but not used [-Werror=unused-but-set-variable]
cc1: all warnings being treated as errors"

This patch removes the unnecessary assignments to the variable, which cause
the compiler warning (used but not set), and build failure, and removes it

I think it's ok to do that, since the variable wasn't actually used anywhere
inside those two functions that caused the warning. Right?
