I have rather large GWT project that depends on a number of third party libraries. When compiling the GWT part of the application, I see that the GWT compiler goes through 10 permutations. But I'm only compiling for 5 different browsers, and for one locale. How can I figure out what is causing the each permutation? Is there some setting I can enable that prints out what each permutation is for when it is compiled. Something that would give me output like:

```
Compiling Permutation 0 - Browser ie8 and Locale En  ....
Compiling Permutation 1 - Browser ie9 and Locale En  ....

```

My gwt.xml file:

```
