(Seethe file ansi2knr.c for full details.) However, since ansi2knr.c is not needed as part of any program generated from theIJG code, this does not limit you more than the foregoingparagraphs do.The Unix configuration script "configure" was produced withGNU Autoconf. It is copyright by the Free Software Foundationbut is freely distributable. The same holds for its supportingscripts (config.guess, config.sub, ltconfig, ltmain.sh). Anothersupport script, install-sh, is copyright by M.I.T. but is also freelydistributable.It appears that the arithmetic coding option of the JPEG specis covered by patents owned by IBM, AT&T, and Mitsubishi.Hence arithmetic coding cannot legally be used withoutobtaining one or more licenses. For this reason, supportfor arithmetic coding has been removed from the free JPEGsoftware. (Since arithmetic coding provides only a marginalgain over the unpatented Huffman mode, it is unlikely that verymany implementations will support it.)So far as we are aware, there are no patent restrictions on theremaining code.The IJG distribution formerly included code to read and writeGIF files.To avoid entanglement with the Unisys LZW patent, GIFreading support has been removed altogether, and the GIFwriter has been simplified to produce "uncompressed GIFs".This technique does not use the LZW algorithm; the resultingGIF files are larger than usual, but are readable by all standardGIF decoders.We are required to state that"The Graphics Interchange Format(c) is the Copyrightproperty ofCompuServe Incorporated.
