Change 92523 by rwatson at rwatson_peppercorn on 2006/02/28 12:41:03

	Test for auditon() system call and provide a compile-time definition
	if it is available; this will make it possibly to not compile some
	run-time audit tools (such as audit, auditd) and components of
	libbsm on systems without the system calls -- otherwise you may get
	linking errors due to undefined symbols.
