Emacs and ImageMagick-7 issues

[Angelo Graziosi]

Just for the record I want to flag the following.

A few months ago, on MSYS2-MinGW64, there was the upgrade from 
ImageMagick 6.x to version 7.x. After this, 'configure' stopped to add 
support for ImageMagick when building Emacs:

Does Emacs use imagemagick?                             no

(with version 6.x it is 'yes').

This seems related to the fact that ImageMagick people has changed many 
file name, adding 'Magick' ahead. For example, 'configure' search for 
Wand.pc but there is MagickWand.pc etc. As consequence, also image.c 
seems broken related to ImageMagick-7.

I think this will regard also other systems when they will upgrade to 
ImageMagick-7, unless that people will revert the naming convention.


Ciao,
  Angelo.
