It would be nice if enums were generated beside string arrays (in the
same order) and these enums were also set be cmdline parser. The
corresponding *_given could store the enum value in case of simple
(not multiple) option if enum offsets start from 1 instead of 0. I
don't know what to do with multiple options now. (Of course, a very
new tag in the cmdline structure would be the most convenient

A little example w/ cmdline.ggo: option  "string-option" s "bla-bla"
typestr="LEVEL" values="off","normal","high" default="normal" no

cmdline.c: char *cmdline_string_option_values[] = {"off", "normal",
"high", 0} ;  /* Possible values for string-option.  */

cmdline.h: enum cmdline_string_options { /*
cmdline_string_option_no_value = 0 -- do we need it? */ cmdline_string_option_off = 1, cmdline_string_option_normal, cmdline_string_option_high };

yes this is very useful, as for multiple options I guess, as you said, a new tab in the cmdline structure would be the best thing.

I'll work on this!
