No, not exactly. You're still your own self, just with the token
extended to contain the Administrators group with SE_GROUP_ENABLED flag
set in the group list, instead of with SE_GROUP_USE_FOR_DENY_ONLY.
But it doesn't really matter. If you're running setup as a user which
is member of the Administrators group, on Vista or earlier, you have the
Administrators group in your user token.

Why? I mean, why should you have a desire to chown the Cygwin tree?
The permissions are the ones from the archive. The owner is the
Admin's group (sort of root, which is probably what you want anyway),
and the files created by postinstall scripts will get the right owner
and permission by the script.
In theory, if we do it that way (assuming solution 3), a chown -R
should never be necessary.

I don't like the idea of additional command line options since it
doesn't help 99% of the users, which are using setup.exe as a GUI-only
tool.
