  The setup.exe on cygwin.com is compressed by upx v2.03 whereas the setup.exe
on ftp.mirror.ac.uk was compressed by upx v2.02.  Can't guess off the top of
my head why that doesn't trigger a redownload.  Here's ftp.mirror.ac.uk:

-rwxr-xr-x    1 ftp      ftp        304128 Sep 08  2005 setup.exe

  Here's cygwin.com:

-rwxrwxr-x  1 cgf cygwin 304128 2005-09-08 16:17:51.000000000 +0000 setup.exe

  I wonder how accurately rsync measures timestamps.  Perhaps some mirrors use
the --modify-window option.



    cheers,
