DESCRIPTION OF BUG: In some cases a bug report will refer to several 
	different problems.  Be specific here about which problem 
	this change fixes.  CSD should be able to use this to write 
	the README file that goes out with the patch.  Remember that
	your audience is CSD and Sun customers.  Put more emphasis on
	the symptoms of the problem then on the reason for it.  CSD
	will use this description to distinguish between similar bugs, so
	give them the information they need to do that,  including 
	what to look for in a corefile if that is appropriate.
FILES MODIFIED: 
	File				SID
FILES AFFECTED: If you edit a header file, other files may have to be 
	recompiled even if they were not modified.
