Further, it appears that Red Hat (Fedora) has chosen to avoid these 
libraries as well.  libmad is available for Mandriva at the Penguin 
Liberation Front; it is available for Fedora over at Freshrpms -- both 
of which are hosted, er, elsewhere and are not discussed or supported on 
official channels.


Side note: I often use an old copy of upset to generate setup.ini's for 
my locally built packages which I store in a cygwin/release tree on my 
private server, and add that URI to my setup.exe's URI list.  I once 
advocated ("RFD: A modest proposal #2: unsupported" 
http://www.cygwin.com/ml/cygwin-apps/2003-04/msg00306.html) having an 
'unsupported' tree on the official mirrors similar to the existing 
'release' tree but that was shot down for good reason.  IIRC at some 
point in the discussion it was pointed out that the existing 
functionality in setup was sufficient to solve the problem I described, 
and much more flexible, and did not require official sanction from the 
cygwin mirror system.
