Are there systems that do not have the equivalent of getenv and
putenv?

An super simple implementation on most unices could result in (f.ex.):

   envir_iterator env(environ);
   envir_iterator end;
   for (; env != end; ++env) {
       pair<string, string> p = *env;
   }

Or do you want to avoid using the system environment?
