I also found this as a possible solution:

class CMyClass
{
	public:
		static int UpdateHelper(void *);
		int Update();
};

int CMyClass::UpdateHelper(void *t)
{
	return ((CMyClass *)t)->Update();
}

...
		UpdateThread = SDL_CreateThread(UpdateHelper, this);
...

That seems cleaner to me, so I'm going to go with this for now and  
change if y'all have a better suggestion.
