What i met is exactly the second case, however one of the environment
variables should be(according to the code):

set EMACSLOADPATH=X:/share/emacs/<version>/site-lisp;X:/share/emacs/<version>/../site-lisp;X:/share/emacs/<version>/lisp;X:/share/emacs/<version>/leim

And with the other two paths, I'll have to repeat the string
"X:/share/emacs/<version>" for six times, by hand. which is exactly
the emacs_dir variable.

"addpm.exe" won't help in this case because it will generate incorrect
path variables in the registry which will be overridden by the code i
mentioned above. At the same time it will overwrite old settings.

So this is a little inconvenient. If you think this case is not TOO
rare, maybe you can consider fixing it from the code?
