Since the directory name itself does not have quotes, I think the right
thing to do is to add the quotes when you generate the shell command,
which is what requires them:

(setq dna-bin-directory "c:/program files/dna/bin")

(setq compile-command
      (format "\"%s\" %s"
              (expand-file-name dna-executable-name dna-bin-directory)
              (file-name-nondirectory buffer-file-name)))

Or perhaps (1) make compile-command a buffer local variable, since its
value is specific to the buffer and (2) use the shell-quote-argument
utility to handle both the program and the file:

(set (make-local-variable 'compile-command)
     (concat (shell-quote-argument
              (expand-file-name dna-executable-name dna-bin-directory))
             " "
             (shell-quote-argument
              (expand-file-name (file-name-nondirectory 
buffer-file-name)))))

That looks like a message from your shell, not Emacs.
