Comment (by michel):

 OK, I figured out what the problem is.
 The problem is caused by the `/Za` compiler option.
 The `/Za` option is buggy and its use is not recommended
 (or rather, you shouldn't use it).
 By removing `/Za`, the warning gets disappeared.
 There is nothing wrong with the code in `transform_iterator.hpp`,
 and I think this warning problem would be "won't fix".

 The solution to this problem is

   **Don't use `/Za`.**

 See the posts from Stephan T. Lavavej (Visual C++ libraries developer)
