ImageMagick 6.0.4 no longer executes with package xorg-x11-bin-dlls 6.8.99.901-1

Hi all,

I have found a problem with ImageMagick 6.0.4 running with 
xorg-x11-bin-dlls 6.8.99.901-1 - and I've found a temporary fix.

Problem:

After a recent update to my Cygwin installation, which updated the X11 
packages amongst many other things, the 'convert' program stopped 
working. It simply exited silently with an error status. I discovered 
with gdb that it was failing with an unknown exception but I could find 
no more information. It turned out, thanks to running 'cygcheck 
convert', that this was because of a missing DLL, specifically 
/usr/X11R6/bin/cygdpstk-1.dll.

A bit more digging and I found that this DLL used to be part of package 
xorg-x11-bin-dlls but has been removed with the latest release - 
6.8.99.901-1. It existed in all versions (as far as I have been able to 
find out) up to this one.

I also discovered that this DLL itself relies on another missing DLL: 
/usr/X11R6/bin/cygdps-1.dll which I found in the same package.

Work-around:

I've fixed the problem for myself by grabbing these DLLs from the 
previous version of this package (xorg-x11-bin-dlls-6.8.2.0) and 
hand-installing them by copying them into the relevant directory. 
Fortunately they are still compatible with the other DLLs they depend on.
