std_memory.h (__get_temporary_buffer): Don't use INT_MAX...

Browse source 
2004-10-09  Paolo Carlini  <pcarlini@suse.de>

	* include/std/std_memory.h (__get_temporary_buffer): Don't use
	INT_MAX, prefer numeric_limits<ptrdiff_t>::max(), ok on 64-bit
	platforms too.
	* testsuite/20_util/memory/auto_ptr/assign_neg.cc: Adjust dg-error
	line numbers.
