I had that problem some weeks ago, using CERNLIB libraries in building fortran programs. (http://cygwin.com/ml/cygwin/2005-12/msg00641.html)
I solved deleting '-lcygipc' from the build command. Also PAW, a CERN application had problems, so I rebuilt all CERNLIB deleting -lcygipc. Now all works fine.
