The truth is that there was a miscommunication between the compiler group
and the people preparing the manual:

	Parallel Programming on Silicon Graphics Computer Systems
	007-0770-010

	at:
	Understanding the Basics of Parallel Programming 
	page 2-9,
	2.2.2 Compiler Flags for Multi-Thread Code

The section is wrong. There is no applicable compiler flag. Please do not
use -align16!

Dan Karron (karron@nyu.edu) noticed that there was something wrong and
brought it to our attention December 26, 1990.  Thanks Dan!

We are sorry about this mistake.
