I guess the right thing to do is to never free arguments passed to 
getopt_long if another call has to be made: this seems to never be safe 
(even because getopt_long can rearrange the elements, as documented).

I uploaded a newer version here

http://rap.dsi.unifi.it/~bettini/gengetopt-2.17rc.tar.gz

I still haven't documented the use of multiple parsers but there's the 
test test_multiple_parsers that can be taken as an example of usage of 
three parsers.

there's the new parser function that can be generated with the gengetopt 
command line

-S, --string-parser         generate a string parser (the string
                                contains the command line)

see the test test_multiple_parsers.c

Of course I switched back to optind = 1

I hope to hear from you soon about this new feature (before I release it)

thanks in advance
        Lorenzo
