long-options: need getopt

[Bruno Haible]

The 'long-options' module includes <getopt.h> and uses 'struct option'.

This yields the following error on HP-UX 11:

        cc -Ae -O -DHAVE_CONFIG_H -I. -I..      -g -c long-options.c
cpp: "long-options.c", line 30: error 4036: Can't open include file 'getopt.h'.

and the following error on OSF/1 5.1 (which apparently has a <getopt.h>
but not the GNU one):

cc -O -DHAVE_CONFIG_H -I. -I..       -c long-options.c
cc: Error: long-options.c, line 36: In the initializer for long_options, an 
array's element type is incomplete, which precludes its initialization. 
(incompelinit)
  {"help", no_argument, NULL, 'h'}, 
--^

I'm applying this fix:

        * modules/long-options (Depends-on): Add getopt.
