[help-gengetopt] updated CVS with (development) version 2.22b

[Lorenzo Bettini]

Hi

I've updated the CVS with the development version I'm still working on.

It includes one patch from Papp (the other one makes some tests fail, 
see my previous email to the list) and the two from David Bryan (as for 
the --help and --version generation in case only the short option is 
redefined, I had to modify also the gm.cc accordingly so that --help and 
--version are actually handled as such)

Version 2.22

   * avoid test suite if crosscompiling
   * generated code is averagely less verbose
   * generate a function to save the command line options into an open 
stream
     (thanks to Papp Gyozo).
   * given fields are unsigned also for non multiple options
   * removed compilation warnings for generated code when using
     -Wstrict-prototypes (thanks to Andre Noll)
   * added print_errors parameters to pass to generated parser function to
     suppress getopt_long message printing (thanks to J. David Bryan)
   * if h is specified as a short option, then --help is still 
automatically
     generated, the same holds for --version and v (thanks to J. David 
Bryan)

as I said, this is version is not definitive

cheers
        Lorenzo
