481.1.9 by Monty Taylor Added autoconf tests for location of cstdint and cinttypes. Use those in C++ programs now, so that we don't have to define _STDC_LIMIT_MACROS, etc by hand. Stop, in fact, defining those by hand.	1	# We check two things: where the include file is for hash_map, and
	2	# what namespace hash_map lives in within that include file. We
