Phil Edwards bf7edb60c8 re PR libstdc++/2054 (g++-3 rejects legal code, accepted by g++-2.95.2 (functors))
2002-01-02  Phil Edwards  <pme@gcc.gnu.org>

	* include/bits/stl_algo.h (upper_bound, equal_range, binary_search):
	Change concept checks, as with lower_bound and PR 2054.
	* testsuite/ext/concept_checks.cc:  Expand test to include those.
