Can be built before the patch or after the patch? 

After the patch.

 

And after it is
built, will it run on a system where ImageMagick is not installed at
all?

My point is : ImageMagick is made available by dynamically loading 2 dlls.

If they are not installed, then the feature is disabled (as far as I remember).

What happens if the jpeg or xpm or png dlls are not found ? 

You see, w32-win.el doesn't have ImageMagick-related DLL names in its
value of dynamic-library-alist, and without that Emacs won't know
which libraries to look for when ImageMagick support is requested.

It is easy enough to add them and if the patch I posted didn't address this issue, 

this is my mistake. Because it is certainly needed.
