Thanks for the confirmation, Dave.  Since Achim can't reproduce the problem, 
maybe we should temporarily forget about local mirrors and go back to the 
simpler situation reported by the OP.  I just reproduced that problem in a 
simpler form as follows:

1. Download setup-x86.exe from the Cygwin website, and put it in an empty 
directory c:/download-test.

2. Run setup-x86.exe.  Choose "Install from Internet".  Choose the nonexistent 
c:\cygwin-test as root directory.   Choose c:/download-test as local package 
directory.  Choose http://mirrors.kernel.org as the only download site. 
Repeatedly click "Next" while setup does a base install.

At this point, the download directory looks like this:

download-test
   setup-x86.exe
   http%3a%2f%2fmirrors.kernel.org%2fsourceware%2fcygwin%2f
     x86
       setup.ini
       release
         _autorebase
         ...

3. Run setup-x86.exe again, this time choosing "Install from Local Directory". 
setup complains that it can't get 
c:/download-test/http%3a%2f%2fmirrors.kernel.org%2fsourceware%2fcygwin%2f//x86/setup.ini.sig 
from <localdir>.  [This is the first bug; if setup expects to find signature 
files in local directories, it should save the ones it downloads.]

4. Retry, this time using setup-x86.exe -X.  The "Select Packages" screen lists 
all the installed packages, but for each package the only options are "Keep" and 
"Uninstall".  [This is the second bug; setup has apparently failed to descend 
into http%3a%2f%2fmirrors.kernel.org%2fsourceware%2fcygwin%2f.]

5. Repeat, but this time change the local package directory from the default 
c:/download-test to 
c:/download-test/http%3a%2f%2fmirrors.kernel.org%2fsourceware%2fcygwin%2f.  Now 
each package has the additional option "Reinstall" (which works).

Achim, can you reproduce this?  Please use the official setup-x86.exe rather 
than the one you built, in case your local setup repo is somehow different from 
the upstream repo.

Ken
