structured-haskell-mode: link Haskell libraries statically into this executable
It's my understanding that Emacs runs the "structured-haskell-mode" binary virtually every time you press a key in an Haskell buffer, and since dynamically linked Haskell binaries take *much* longer to start up, switching this particular package to statically linked libraries ought to result in a performance boost.
