CMake 2.4.6-1 ready

[Bill Hoffman]

There has been a new release of the official cmake (2.4.6-1).
This is a minor release from to 2.4.5 to 2.4.6.

Here are the required files:

http://www.cmake.org/files/cygwin/setup.hint
http://www.cmake.org/files/cygwin/cmake-2.4.6-1.tar.bz2
http://www.cmake.org/files/cygwin/cmake-2.4.6-1-src.tar.bz2

The previous version should be cmake-2.2.3-1 and the current
version should be cmake-2.4.6-1.

Thanks.
