gengetopt: bug found in gm.cc:584

Hi all,

I found a bug when using --long-help, I have used genpetopt 2.17
(manually installed on a mandriva 10.1), with and without my last patch,
and the gengetopt shipped with my distro (2.12.2). All these version
lead to the bug.
I have added this printf below the bug location:
fprintf (stderr, "typestr=%s, @typestr=%p, short_opt=%s, long_opt=%s,
opt_type=%d\n", type_str, type_str, opt->short_opt, opt->long_opt,
opt->type);

[chgans@pc-laurent tmp]$ gengetopt --version
GNU gengetopt 2.17
[...]
[chgans@pc-laurent tmp]$ cat bug.ggo
option "option-noarg" - "option with no arg" required
[chgans@pc-laurent tmp]$ gengetopt < bug.ggo
[chgans@pc-laurent tmp]$ gengetopt --long-help < bug.ggo
