We do have "placards" in several places that indicate that nsc is not
supported in Cygwin.  However, the current situation with what someone would
see if they tried to enable nsc support in the case of Cygwin is Bad (TM).  

As it stands, you can --enable-nsc and waf will happily download NSC and
tell you that it is enabled.  When you build the tree, waf will happily
start compiling, but produce a build error in scons that propagates back to
waf and our unhappy user sees:

  scons: building terminated because of errors.
  Building NSC stack failed

So it appears like we have a build error and not an unsupported
configuration at all.

We are doing a build system refactoring for ns-3.4 and a better indication
of what is going on should make it in to that project.
