commit 59803a8928076463096fbaa8834ee15cd63852f9
Author: William Cohen <wcohen@redhat.com>
Date: Mon Jul 9 15:25:42 2012 -0400
Remove the unused variable assignments for getenv() calls
There were a number of places in the code that assigned the return value
of getenv to a variable. However, the variable was never used in most cases.
This patch cleans up those unneeded assignments.
