Setup bug --- probably already reported and fixed, of course

[Harold L Hunt II]

FYI --- In further testing, archive.progeny.com is the mirror that has 
not been updated yet.  Selecting only archive.progeny.com gives me the 
warning about setup.ini being older than when I last installed Cygwin. 
Selecting only mirrors.rcn.net does not give such a warning and 
correctly indicates that the XFree86-bin tarball is roughly 10500 KiB 
and downloads it and all other tarballs with no problems.  Thus, this 
does not so far appear to be entirely my fault.
