OK, never mind, it seems to be merely a bug of g++, as the errors mysteriously
disappeared after I moved the class-definitions out of stl_algorithm_class.
so, not template<template was the problem, but telling g++ that I wish to
access a class-definition within another class seems to be impossible when
templated templates are involved...
