I'm curious - did you bring this up with them before posting here? Knowing xdg and Alias, they would be absolutely delighted to get patches and improvement suggestions, particularly when you have links like you do in this post. As for g77, it may be that no-one needed it before you. So, if you were to provide a bundle with the g77 compiler back to Dave and Adam, I think they'd be pretty happy with that.
My criteria for good software:
Does it work?
Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
