The first effect are a lot of undefined references when linking. Those references point to libsupc++ which in turn has only a few dependencies to libc. Besides adding the lib there are also runtime costs I suppose which one wants to avoid (or at least know exactly where they are). Overall it is not necessary to require this functionality, at least for us.
