Yah, right.  And I'd suppose that you think the following is also
legal and not a "preprocessor game":

#include "pascal.h"

main()
BEGIN
	int foo;

	IF (foo) THEN
	BEGIN
		WRITE ("Fooing today\n");
	END
	ELSE
	BEGIN
		WRITE ("No foos today\n");
	END
END

The above, while strictly speaking IS 'C' (depending on the defines in
pascal.h, that is), I'd hate to have to maintain something like that.
#define EXTERN extern is a gross preprocessor game that should be
avoided, just as the above cute pascal example should be avoided.
