Cygwin packages available on dronecode

Since it's now much easier to install packages from additional repositories using Cygwin setup, I suppose I should mention what's available from http://www.dronecode.org.uk/cygwin/

As well as using that to stage releases of the Cygwin/X xorg-server package to test they are installable, it also has a few packages which might be of use to someone:

• mesademos containing all the mesa OpenGL demo and test programs
• xscreensaver useful for OpenGL testing, not so much as a screensaver.  It's left as an excercise for the reader to write a native .scr screensaver which starts an X server using  -displayfd and then runs the X screensaver on that server :-)
• glean OpenGL test and benchmarking suite
  
• buildbot-slave
• llvm and llvm-gcc some experimental llvm packages
