Longhi <<a href="mailto:aldo.longhi@alum.wpi.edu">aldo.longhi@alum.wpi.edu</a>>).</li> <li> test suite added (type <i>make check</i>, to run the tests).</li> </ul> <h2> Changes in release 2.2</h2> <ul> <li> scanner is simplified and now accepts arbitrary character strings between, thanks to <a href="mailto:nbecker@fred.net">nbecker@fred.net</a>.</li> <li> It compiles under Sun C compiler 5.1, thanks to Robert Walsh <<a href="mailto:Robert.J.Walsh@eng.sun.com">Robert.J.Walsh@eng.sun.com</a>>.</li> <li> VERSION and PACKAGE are generated in cmdline.h instead of cmdline.c, thanks to Richard Heggs <<a href="mailto:richard@virtua-web.co.uk">richard@virtua-web.co.uk</a>>.</li> <li> #undef's PACKAGE and VERSION before setting them, in case they are defined in the .ggo file, thanks to Scott Haug <<a href="mailto:scott@id3.org">scott@id3.org</a>>.</li> <li> long options with no associated short options are allowed, thanks to <a href="mailto:damned@world.std.com">damned@world.std.com</a>.</li> <li> fixed no_getopt_long.txt, thanks to Peter Fox <<a href="mailto:fox@roestock.demon.co.uk">fox@roestock.demon.co.uk</a>></li> </ul> <h2> Changes in release 2.1</h2> <ul> <li> It is made more clear that use of gengetopt <u>does not impose any particular license on the generated code</u>.</li> <li> A bug in the generation of code (for some new C++ compilers) was fixed, thanks to "James R. Van Zandt" <<a href="mailto:jrv@vanzandt.mv.com">jrv@vanzandt.mv.com</a>></li> <li> Some modifications to the man page, also due to James.</li> <li> a directory for examples is specifically created (suggested by James).</li> </ul> <h2> Changes in release 2.0</h2> This is quite a totally new release: <ul> <li> Gengetopt has become GNU software</li> <li> it is conform to GNU coding standards, and so it uses configure script generated by Automake and Autoconf</li> <li> it generates separated files: one header file with the struct used to store command line options information, and a C file which contains the function which actually uses getopt_long to parse the command line</li> <br>'required' option is now fully implemented</ul> </body> </html>
