code if you redistribute it. (See the file ansi2knr.c
for full details.)
However, since ansi2knr.c is not needed as part
of any program generated from the IJG code,
this does not limit you more than the foregoing
paragraphs do. The Unix configuration script
"configure" was produced with GNU Autoconf.
It is copyright by the Free Software Foundation
but is freely distributable. The same holds for its
supporting scripts (config.guess, config.sub,
ltconfig, ltmain.sh). Another support script,
install-sh, is copyright by M.I.T. but is also freely
distributable.
It appears that the arithmetic coding option of
the JPEG spec is covered by patents owned by
IBM, AT&T, and Mitsubishi. Hence arithmetic
coding cannot legally be used without obtaining
one or more licenses. For this reason, support
for arithmetic coding has been removed from
the free JPEG software. (Since arithmetic coding
provides only a marginal gain over the unpaten-
ted Huffman mode, it is unlikely that very many
implementations will support it.) So far as we are
aware, there are no patent restrictions on the
remaining code.
The IJG distribution formerly included code to
read and write GIF files. To avoid entanglement
with the Unisys LZW patent, GIF reading sup-
port has been removed altogether, and the GIF
writer has been simplified to produce "uncom-
pressed GIFs". This technique does not use the
LZW algorithm; the resulting GIF files are larger
than usual, but are readable by all standard GIF
decoders. We are required to state that:
"The Graphics Interchange Format(c) is the

ted. GIF(sm) is a Service Mark property of Com-
puServe Incorporated."
