[svn-r4688]

Purpose:
	Bug Fix
Description & Solution:
	In the test for "namespace", we needed to include the "iostream"
	header file to remove errors for strict compilers who need iostream
	for namespaces. I moved the test for namespace to after the test for
	"old header filenames" to make sure that I'm #including the correct
	iostream ("iostream" or "iostream.h").
Platforms tested:
	Linux
