The difference between 32-bit and 64-bit is due to differences in 
ImageMagick on the two platforms.

On 32-bit, as I showed in an earlier message, I get:

$ objdump -p /usr/bin/cygMagickCore-6.Q16-2.dll
[...]
         DLL Name: cyggd-3.dll
         vma:  Hint/Ord Member-Name Bound-To
         48ee2c      8  WebPDecode
[...]

On 64-bit, I get:

$ objdump -p /usr/bin/cygMagickCore-6.Q16-2.dll
[...]
         DLL Name: cygwebp-5.dll
         vma:  Hint/Ord Member-Name Bound-To
[...]
         48096c    271  WebPDecode
[...]

Moreover, libMagickCore6_2 depends on libgd3 on 32-bit but not 64-bit. 
So it seems that ImageMagick needs to be rebuilt on 32-bit so as to 
remove this dependency.
