DR 538, [Ready]

2006-04-10  Paolo Carlini  <pcarlini@suse.de>

	DR 538, [Ready]
	* include/bits/stl_algo.h (__unique_copy(,,, input_iterator_tag,
	output_iterator_tag), and predicated counterpart): Revert to the
	algorithm pre-DR 241, i.e., value_type of InputIterator is now
	required to be Assignable too.
	* testsuite/25_algorithms/unique_copy/3.cc: Remove.
	* docs/html/ext/howto.html: Add an entry for DR 538.
