Unresolved problems, to be fixed later: * Commented out test in go/types/sizes_test.go that doesn't compile. * Commented out reflect.TestStructOf test for padding after zero-sized field. Reviewed-on: https://go-review.googlesource.com/35231 gotools/: Updates for Go 1.8rc1. * Makefile.am (go_cmd_go_files): Add bug.go. (s-zdefaultcc): Write defaultPkgConfig. * Makefile.in: Rebuild.
