Compiler doesn't push a binding for *unchecked-math*
Compile.java in Clojure doesn't push a binding for unchecked-math, so compilation of code with statements like (set! unchecked-math true) fails with:
Can't change/establish root binding of: unchecked-math with set
This problem doesn't happen with the REPL because with-bindings in clojure.main sets up an unchecked-math binding.
