Sure, will do after I go home tonight. Also the "Segmentation fault" bug
that I'll report later.

That didn't work, but 

  gcc -DPACKAGE='"..."' -DVERSION="..."

OK, here are the things need to be changed:

| From /usr/share/doc/gengetopt/examples/README.example:
| ... 
| # commands to try the C example: 
| gengetopt --input=sample2.ggo --func-name=my_cmdline_parser 
| --file-name=cmdline2 --unamed-opts
| gcc -o main2 main2.c cmdline2.c
| ./main2 -h
| ... 

the C example that come with the Debian/Ubuntu package
was generated with a different command line: 

 gengetopt --input=./sample2.ggo --func-name=my_cmdline_parser 
--file-name=cmdline2 --unamed-opts --no-handle-help --no-handle-version

To compile, 

  gcc -DPACKAGE='"cmdline2"' -DVERSION="1.1" -o main2 main2.c cmdline2.c
