The cause was an UAC issue.

I am new to W7 (64) so I am trying to setup it as on XP (32). More 
precisely, I have chose the local Cygwin repository in 
$HOME/cygwin_repo, being $HOME the HOME of the administrator (angelo). 
And, after the first installation (in which I got the UAC request), I 
have put setup-x86[_64].exe in the local repo. Cygwin32 is installed in 
C:\cygwin while Cygwin64 is in C:\cygwin64. I use the same repo for both 
(they are separated in MIRROR/x86[_64])

So, to install/update packages, I do:

Start|Run

  C:\cygwin\home\angelo\cygwin_repo\setup-x86.exe       (Cygwin32)
  C:\cygwin\home\angelo\cygwin_repo\setup-x86_64.exe    (Cygwin64)

Now, starting setup-x86_64.exe asks me always the UAC confirmation, 
instead setup-x86.exe don't! It run without administrator permissions. 
And this causes the failure described in my OP.

The workaround has been to move setup-x86.exe in the parent directory, i.e.


  Start|Run

  C:\cygwin\home\angelo\setup-x86.exe

asks me the UAC confirmation, it really run as administrator.

What I don't understand is why moving setup-x86.exe in that way fixes 
the issue. I have also removed cygwin_repo and recreated but 
setup-x86.exe needs to stay above cygwin_repo... This regard only 
setup-x86.exe and not setup-x86_64.exe.. :(
