I just took a bit of a deeper look at this issue...

So, in the dash14 cygwin dashboard MINGW is not set as expected for the 
cygwin build.  For the dash14 Mingw build, MINGW is being set in CMake.

However, Brad's change here:

http://public.kitware.com/cgi-bin/viewcvs.cgi/CMakeLists.txt?root=Insight&r1=1.344&r2=1.345

Does not seem to be working for either the Mingw or the Cygwin build... 
   I do not see those flags being used in the makefiles even on the 
Mingw build even though MINGW is set.  It might be a cmake 2.6.4 issue. 
  Bill what version CMake/gcc/cygwin do you have this running without 
warnings?
