Michele,

	I was able to try a build of MaxCut on cygwin.  The problem lies in
Makefiles/Makefile.CYGWIN.  At the top of the file you'll see the lines

CXX := g++  -mno-cygwin
FF  := g77  -mno-cygwin

Change these lines to read

CXX := g++ 
FF  := g77

(MaxCut doesn't use Fortran, but fixing the FF definition can't hurt.)  This
fixes the problem on my local cygwin system --- I was able to build and run the
example.  You'll need to remove all executables and library files and rebuild
from scratch for consistency.

The -mno-cygwin option produces executable files which will run in a standard
Windows environment (i.e., the executable does not depend on libraries that are
only available in the cygwin environment).  This is a good thing, but my
knowledge of BCP is not sufficient for me to do a quick fix that incorporates
-mno-cygwin.
