I have some speculation on the behavior of the compilers, but no REAL answers.
Here's another PCC peculiarity that someone discovered recently:
} xyz;
struct	xyz Xyz;
	many references to xyz, none to Xyz;
The PCC repeorted NO errors, the Ritchie compiler correctly tagged the
	struct xyz Xyz;
as an undefined structure `xyz' .
Speculation: The PCC would have checked the validity of the structure
definition when a reference was found to that structure.
	Perhaps Dennis and Steve Johnson would like to explain this
apparently anomalous behavior?
