It depends on how you are including the JavaScript source. If it is a <script> tag in the .gwt.xml or the html host page, the GWT compiler barely knows it exists, and will do nothing with it. Likewise, if you use the ScriptInjector to make it available to the app, either from a url, or from a String or External/TextResource - as far as GWT can tell, its just a String.
If on the other hand you put it into a JSNI method, the compiler will understand that it is source and should be optimized as much as possible. Note however that JSNI is limited in how it can be optimized, though enabling the Closure compiler can often do a more comprehensive job of cleaning up that JS source, though this cleanup may in some cases break code that isn't prepared to be optimized in that way.
