Hmm... I don't understand...

I have built Emacs with CLANG since this was added to Cygwin. First on 
Cygwin32 and now on Cygwin64, and it always worked O(other_bugs)... Only 
after the last ImageMagick update the build is broken...

In any case, also GCC seems to have the same problems:

[...]
Configured for `x86_64-pc-cygwin'.

   Where should the build process find the source code?    .
   What compiler should emacs be built with?               gcc

   Should Emacs use the GNU version of malloc?             only before 
dumping

Sure it isn't a packaging bug? I see that now ImageMagick has missed 
/usr/lib/libMagickCore.dll.a... and this

cd /usr/lib
ln -sf libMagickCore-6.Q16.dll.a libMagickCore.dll.a

seem to fix the build (both with CLANG and GCC)


Ciao,
  Angelo.
