I'm not sure if it's necessary, but it should still work with it.

I'm not sure. AFAIK, it's supposed to be, but I'm not sure how well 
tested that is or how easy it is to do.

The gcc spell (4.6.3, this was removed from 4.7.2 for some reason) 
actually downloads ecj.jar and uses that. The version in the gcc spell 
is pretty old and there is a newer version. FYI Gentoo still uses 
ecj.jar for gcc 4.8, so there is a good chance it shouldn't have been 
removed.

Once you get gcj, you should be able to compile ecj.
