Dart2js no longer considers duplicate library names as an error, but it also doesn't seem to give the required warning.

lrn@: Do you have a repo? We have code and test for the issue so something is checked.

The missing warning may be due to my script-to-run-dart2js not showing the warning if compilation otherwise succeeds. When I run sdk/bin/dart2js directly, there is a warning.
