GD does look like it would work for me and there is a pre-compiled windows library for it at
http://www.boutell.com/gd/manual2.0.33.html#getgd (NOTE: the library file there is called "bgd.dll" instead of "gd.dll".)
I'm able to compile cl-gd-glue-gif.c ok with gcc -Id:/local/graphics/gd/gdwin32 -c cl-gd-glue-gif.c
Unfortunately, I'm not able to link cl-gd-glue-gif.o, see below. Apparently six years of Java have atrophied my windows' C skills down to the most basic level.
Thanks to Harley and Edi for their help, but it looks like I'll need to spend some time relearning basic C linking before I get on with GD & cl-gd.

This may come a bit too late but I had some spare hours today and managed to build GD with MingW. I rebuilt it with __cdecl instead of __stdcall and put the code of cl-gd-glue-gif.c (with the proper declarations) directly into gd.c. (Some fiddling was needed because the configure script didn't find the freetype library although it was there but basically it worked fine.) The result is here: <http://weitz.de/files/cl-gd-glue.dll> This is based on GD 2.0.33 and works fine for me with AllegroCL 6.2 trial and LispWorks 4.3.7 pro on Windows XP pro SP2. In order to use it you should do the following: 1. Download the file from above and put it into the CL-GD folder. 2. Download all the necessary support libs from the GnuWin32 project - see <http://gnuwin32.sourceforge.net/> - and put the corresponding DLLs into the folder where your Lisp image starts up (or somewhere else where your FFI will find them). 3. No need to download bgd.dll (the GD library) itself because it's already part of cl-gd-glue.dll. 4. (push :cl-gd-gif *features*) in order to get GIF support (which is compiled into the DLL). 5. Compile and load CL-GD, make sure to remove old FASL files in case you had previously built CL-GD without GIF support. That's it. If you run the tests you'll see three failed tests but no error messages. This is OK - see the CL-GD documentation for details. Let me know if this works for you. If I'm not the only one who succeeds with this setup I'll update the CL-GD docs accordingly. Cheers, Edi.
