CMake 2.4.7-1 ready

[Bill Hoffman]

OK, I have figured out what happened.  CMake 2.4.7-1 was the first release
of cmake done with cpack for cygwin.  It was not generating gnu style 
tar files.
I have changed that, so it should work with setup now. 

Corinna, can you please upload:

http://www.cmake.org/files/cygwin/cmake-2.4.7-2.tar.bz2
http://www.cmake.org/files/cygwin/cmake-2.4.7-2-src.tar.bz2

cmake-2.4.7-1 should be removed as it does not work with setup.

Thanks for all the help.
