Do not use libc.a  They are already in libcygwin.a.

Yes, I had compiled a few packages which use ONC-RPC/XDR.
You will need 
ftp://ftp.franken.de/pub/win32/develop/gnuwin32/cygwin/porters/Vinschen_Corinna/B20/sunrpc-4.0cygwin1.bin.tar.gz 
  
and http://www.ipass.net/~ssiddiqi, if you are calling XDR routines  from Fortran
