Hello,

This program:

	main()
	{
		void f(char *);

		f("hello\n");
	}

	f(char *s)
	{
		printf("%s", s);
	}

produces, with 'prof -d' the following output:


main:0
.  printf:0
.    vfprintf:0
.  qlock:0
.  .  lock:0
etc.

This indicates that 'main' calls 'qlock', but I
think that 'qlock' is actually called by 'vfprintf'. (?)

Another question: has anyone done anything with the
compiler to generate a static flow graph -- something
like 'cflow'?
