Since Andy McFadden was able to compile the jpeg v3 source with APW C with no modifications, would anyone care to try to port jpeg v4? By the way, the GS port of version 3 works best if you use the -g (for grayscale) and -G (for .GIF) options in djpeg. It will take a LONG time, but not forever. Many of the resulting grayscale GIFs are some of the best I have ever seen on a //GS. --
