configure does not thoroughly test for ImageMagick includes |

Version: 24.0.50
Severity: minor
I tried to build the current trunk on a RHEL 4.8 system.
This has ImageMagick 6.0.7 installed.
configure decided that ImageMagick was usable:
checking for Wand... yes
checking IMAGEMAGICK_CFLAGS...
checking IMAGEMAGICK_LIBS... -lWand -lMagick
checking for MagickExportImagePixels... no
[...]
Does Emacs use imagemagick? yes
However, the build failed because of this:
image.c:7455:29: warning: wand/MagickWand.h: No such file or directory
The system has /usr/include/wand/magick_wand.h, but it does not
have /usr/include/wand/MagickWand.h. Looks like the former is now
deprecated. The latter does exist on RHEL 5.5, with ImageMagick 6.2.8.
Obviously I can just re-configure using --without-imagemagick, but
Emacs should do this for me. Either configure should test for some
required minimum version of ImageMagick (I was not able to find out in
what version wand/MagickWand.h was added); or image.c should fall back
to wand/magick_wand.h if it can.
