I've tested 2.22b with the programs that prompted my initial request for 
enhancements:

 1. Auto-generation of "--help" now works even if I specify a "-h" option.

 2. Suppressing the error message from getopt_long works.  The new
    parameter default initializer works too.

 3. Specifying "values" with "enum" and "int" types works.  I didn't test
    the other types.

Thanks for these!

There is one small issue.  If I have a .ggo file that does not contain any 
option statements, compiling the generated parser gives this warning from 
gcc: 'update_arg' defined but not used.  It would be nicer if this function 
was not emitted in this case.

(Why would I want a .ggo file that has no option statements?  Because I 
want the parser to handle "--help" and "--version" automatically, and the 
program either uses no other options, or the other options are handled 
explicitly by the program and not by the parser.)

Otherwise, all looks very good.
