stl_construct.h (_Construct): Change to variadic in C++0x mode, consistently with allocator::construct. 

2010-06-16  Paolo Carlini  <paolo.carlini@oracle.com>

	* include/bits/stl_construct.h (_Construct): Change to variadic in
	C++0x mode, consistently with allocator::construct.
	* include/bits/stl_uninitialized.h (__uninitialized_copy_n): Use
	_Construct.
	(__uninitialized_construct_range): Move to...
	* include/bits/stl_tempbuf.h (__uninitialized_construct_buf): ... here.
