imagemagick support on W32

[Christoph]

I am trying to get imagemagick working on Windows. I added the support 
to the configure.bat file, downloaded the W32 package from the 
ImageMagick website and supplied the headers and libraries to 
configure.bat, like this:

configure.bat --no-cygwin --enable-checking --with-gcc --distfiles 
D:/devel/emacs/libXpm-3.5.8/src/libXpm.dll --cflags 
-IC:/Progra~2/GnuWin32/include --cflags 
-ID:/devel/emacs/libXpm-3.5.8/include --cflags 
-ID:/devel/emacs/libXpm-3.5.8/src --cflags 
-IC:/Progra~2/ImageMagick-6.6.4-Q16/include --ldflags 
-LC:/Progra~2/ImageMagick-6.6.4-Q16/lib --ldflags -lCORE_RL_wand_ 
--ldflags -lCORE_RL_magick_

I get the following output on `mingw32-make boostrap':

It seems like the linker cannot find the libraries provided despite the 
options point to the right location.

Looking at the gcc call above, it looks like my modifications to 
configure.bat are correct and the options are parsed out correctly.

I tried compiling an example from the ImageMagick website (wand.c) with 
ming32-gcc and the libraries seem to work fine.

Has anybody else tried this and got it to work? I can provide a patch 
bundle with my changes if anybody wants to test.
