stl_deque.h (deque<>::resize, [...]): Avoid troubles with ADL, user defined operators and _Deque_iterator.

2005-12-19  Paolo Carlini  <pcarlini@suse.de>

	* include/bits/stl_deque.h (deque<>::resize, _M_fill_assign):
	Avoid troubles with ADL, user defined operators and _Deque_iterator.
	(operator-(const _Deque_iterator<>&, const _Deque_iterator<>&):
	Add overload for left and right iterators of the same type.
	* include/bits/deque.tcc (erase(iterator)): Avoid troubles with ADL,
	user defined operators and _Deque_iterator.
	* testsuite/23_containers/deque/types/1.cc: Add.
	
	* include/bits/deque.tcc (_M_insert_aux(iterator, size_type,
	const value_type&)): Qualify with std:: fill call.
