[Boost-users] A bit off topic, turning off ScopeGuard warnings in g++

Ok this is bit off topic since it isn't directly related to boost, but I know there are a lot C++ guru's here, and I'm sure one of you has addressed this. I am using Andrei's ScopeGuard and not boosts. I have googled, but I haven't figured out how to turn off the "unused variable" warning in g++, with out disabling all warnings. My guess is that there is no solution, but I thought I would try here first. TIA, Christopher
