Very nice, thank you very much.

Is there a reason to use the custom parser only from
cmdline_parser_configfile() but not from cmdline_parser()?

Yes, that'd be interesting. From the cvs changelog I see that Uli
and Roland McGrath are the main authors of the getopt code in glibc.

One minor thing: There's a missing 'void' in src/skels/c_source.h_skel
for which causes gcc to spit out

        warning: function declaration isn't a prototype

Trivial fix below.
