As I mentioned, I was adding extra packages to Cygwin to get the makefile
version to work. I added the compiler packages (gcc), cmake, and make. (just
to make sure).  That seemed to be what I need, as the "make, make-install, &
make install-info" chant now works and I have a working version of 6.21b.

So, to summarize:
1. download and install the current emacs binaries (I used the W32 version
at http://ourcomments.org/Emacs/EmacsW32Util.html). In my case I installed
to C:\Apps\Emacs.
2. download and install the current version of cygwin. During the install,
you will be asked which packages to install. Choose the develop branch and
install make. (I also installed gcc and g77)
3. unzip the org zip file under C:\Apps\Emacs\site-lisp
4. change directory to C:\Apps\Emacs\site-lisp\org-6.21b (or the current
version)
5. edit the Makefile. these are the changes I made:
EMACS=/cygdrive/c/Apps/Emacs/emacs/bin/emacs.exe

# Where local software is found
prefix= /cygdrive/c/Apps/Emacs/

# Where local lisp files go.
lispdir =  /cygdrive/c/Apps/Emacs/emacs/lisp/textmodes

# Where info files go.
infodir =  /cygdrive/c/Apps/Emacs/emacs/info
6. cross fingers and
make
make install
make install-info
   for the most part I got lots of text from emacs as it started, added
stuff to the path and compiled the individual files. I did get several
warnings about variables being out-of-date.
7. modify your .emacs file as suggested in the manual and save.
8. restart emacs and load an org file. Choose org->Documentation->Show
Version from the menu and the little message area on the bottom should show
"Org-mode version 6.21b"
9. Possible gotchas:

   - a. I somehow ended up with a .../lisp/org directory containing version
   6.06. I don't know if that was my doing or it came with the distribution. I
   used bash to mv all the org* files from lisp/textmodes to lisp/org and then
   got the correct version. On Aquamacs (OS X) the org files end up in
   lisp/textmodes.

If there is a better way, I'd appreciate knowing it.
