 * _HasNetRoot			// network root 	(Domain/OS only)
 * _HasOpenMode			optional mode parameter in open() system call
 * _HasSymLinks			symbolic links 		(BSD file systems)
 * _HasSystemProfile		custom system configuration profile exists
 * _HasIncludeDirent		#include <dirent.h>	(SYSV)
 * _HasIncludeSysDir		#include <sys/dir.h>	(BSD)
 * _HasIncludeSysNdir		#include <sys/ndir.h>	(ndir library)
 * _HasIncludeStrings		#include <strings.h>	(BSD)
