Bug#45288: pb2 returns a lot of compilation warnings on linux
Fix warnings flagged by the new warning option -Wunused-but-set-variable that was added to GCC 4.6 and that is enabled by -Wunused and -Wall. The option causes a warning whenever a local variable is assigned to but is later unused. It also warns about meaningless pointer dereferences.
