It's not directly an answer to your question but you can write this

template 
static T safeGuiCall(boost::function _f)

        {
                ThreadGuard g;
                return _f();
        }
}

It should work even if _f() return 'void'

Edit : In a more general case, I think we should prefer function overloading instead of specialization. Here is a good explanation for this : http://www.gotw.ca/publications/mill17.htm
