On 27 March 2010 I finished my 32-bit DOS port of Eddie Kohler's Gifsicle version 1.59 using DJGPP version 2.04 beta.
Binaries, user manuals in ASCII format, and fully configured sources plus some simple instructions on how to rebuild are available at http://www.bttr-software.de/ports/.
Changes from 1.52 to 1.59:
* gifsicle -O2: Optimize away entirely-transparent frames when possible.
Requested by Gerald Johanson.
* gifsicle: Fix optimizer bug reported by Dion Mendel.
* gifsicle: Don't throw away totally-cropped frames with 0 delay, since
most browsers treat 0-delay frames as 100ms-delay frames. Reported by
Calle Kabo.
* gifsicle: Fix --crop-transparency for animated images; previous versions
could lose frames. Problem reported by Daniel v. Dombrowski.
* gifview: Make --disposal=background behavior look like Firefox.
* gifsicle: Another optimize fix for --disposal previous. Reported by
Gerald Johanson.
* gifsicle, gifview: Fix several serious bugs with --disposal previous that
could affect optimized, unoptimized, and displayed images. Reported by
Gerald Johanson.
* gifsicle: Frames in an unoptimized image will use disposal "none" when
possible. This leads to fewer surprises later.
No DOS or DJGPP specific changes were required. ---
