The new comparison rule was added to the spec by

	changeset:   5605:33abb649cb63
	user:        Robert Griesemer <gri@golang.org>
	date:        Thu Jun 03 16:55:50 2010 -0700
	files:       doc/go_spec.html
	description:
	go spec: Base comparison compatibility on assignment compatibility.

	Specifically:
	- Simplified definition of comparison compatibility and folded into
	  section on comparison operators since it's only used there.

	This is a small language change/cleanup. As a consequence:
	- An interface value may now be compared against a non-interface value.
	- Channels with opposite directions cannot be compared directly anymore
	  (per discussion with rsc).

This test is supposed to test runtime behaviour.  However,
gccgo is smart enough to see that the variables are local to
the package and that they never change.  Add a function so
that gccgo thinks that the variables can in fact vary, so that
the test works at runtime as expected.

If you look at the sequence of values returned
by waitpid, it simply tells us about the child of
clone before it tells us that the parent called clone.
There's nothing we can do but assume unexpected
tids are newly cloned children.

Tested with 6prof on godoc.

The panic NaN was a translation error.
The earliest version said panic "return sys.NaN()",
and when sys.NaN came along, it changed
to "panic sys.NaN()" instead of "return sys.NaN()".
