turn on :aot and warn-on-reflection for :dev

Sorry about the reflection warning noise, but I was having trouble
getting this to compile and aot and warn-on-reflection helped me find
the problem.

Feel free to nuke this commit if you don't like the noise.
fix compile error in environ-auth

This function doesn't seem to be used here, but maybe is in other
projects?

If not, maybe it should be deleted? I don't really know what it's for, I
just ran into the compile error.

It came from pull request #42, so I guess it's important.

This reverts commit 5b1ed7c845ff65d21fa32623e79a8a064bc7bd0e.

I didn't notice this change was made in the pull request. I don't want
reflection warnings turned on unless they're turned on in a pull request
that fixes all of the warnings produced by it. ;)
