GNU gengetopt users?

[tgate]

Has anyone had luck using gengetopt ( http://www.gnu.org/software/ 
gengetopt/ ) for parsing command line options?
I've tried to use it and it seems to create correct cmdline.h and  
cmdline.c files but perhaps I'm not using them correctly because when  
I try a test all I get is this error:

        error: 'gengetopt_args_info' undeclared (first use in this function)

even though it is a struct declared in the cmdline.h file.
