I haven't looked at the source, but the gc compiler appears to omit "not used" errors when there is an error in the initializer. This is harder to do in gccgo, and frankly I think the "not used" error is still useful even if the initializer has a problem. This CL tweaks some tests to avoid the error, which is not the point of these tests in any case. R=golang-dev, r CC=golang-dev https://golang.org/cl/5561059
