Actually it doesn't.  Since calling stat requires you to include
sys/stat.h, you can make both old programs and old .o files work.
Basically, there would be a macro "stat" which gets mapped to say
"_stat2" in the new stat.h that references a new name.  The library
would have both entry points.  Old .o's would go to the old name
"stat", and new ones would go to "_stat2".  Ie:

	#define	stat	_stat2
