PCC compiler bug and odd solution

[Kenneth Almquist]

A piece of code which caused the compiler to exhibit the same behavior
was posted to net.lang.c a couple of weeks ago.  The code looked like:

	struct s {
		int x ;
	}

	subr(p, q) struct s *p, *q ; {
		*q = *p ;
	}

Because the semicolon after the declaration of "s" was omitted, the routine
"subr" is declared to be a routine returning a structure s rather than a
routine returning int.  The missing semicolon would have been caught by
the compiler if "subr" had been declared to be of type "void".
