No question a list like this is bound to be incomplete, but the argument "the README can only tell about those which we don't expect to be installed on a developer's box" does not seem to apply to the other items already on the list. For instance build-essentials and automake are almost certainly on every developers machine already.

I have a fix in a branch here: https://github.com/drichardson/gpg4win/tree/fix-missing-zh-readme
