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.
