Make getopt act the same regardless whether the app was staticly linked
or dynamicly linked.  Obeys the principle of least surprise.

If you set `opterr' to -   zero, the error message is suppressed but we still return '?'. - -   If a char in OPTSTRING is followed by a colon, that means it wants an arg, -   so the following text in the same ARGV-element, or the text of the following -   ARGV-element, is returned in `optarg'.  Two colons mean an option that -   wants an optional arg; if there is text in the current ARGV-element, -   it is returned in `optarg', otherwise `optarg' is set to zero. - -   If OPTSTRING starts with `-' or `+', it requests different methods of -   handling the non-option ARGV-elements. -   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. - -   Long-named options begin with `--' instead of `-'. -   Their names may be abbreviated as long as the abbreviation is unique -   or is an exact match for some defined option.  If they have an -   argument, it follows the option name in the same ARGV-element, separated -   from the option name by a `=', or else the in next ARGV-element. -   When `getopt' finds a long-named option, it returns 0 if that option's -   `flag' field is nonzero, the value of the option's `val' field -   if the `flag' field is zero. - -   The elements of ARGV aren't really const, because we permute them. -   But we pretend they're const in the prototype to be compatible -   with other systems. - -   LONGOPTS is a vector of `struct option' terminated by an -   element containing a name which is zero. - -   LONGIND returns the index in LONGOPT of the long-named option found. -   It is only valid when a long-named option has been found by the most -   recent call. - -   If LONG_ONLY is nonzero, '-' as well as '--' can introduce -   long-named options.  */ - -#if NLS -#include "nl_types.h" -#endif - -int -_getopt_internal (argc, argv, optstring, longopts, longind, long_only) -     int argc; -     char *const *argv; -     const char *optstring; -     const struct option *longopts; -     int *longind; -     int long_only; -{ -  optarg = NULL; - -#if NLS -  libc_nls_init(); -#endif - -  if (optind == 0) -    optstring = _getopt_initialize (optstring); - -  if (nextchar == NULL || *nextchar == '\0') -    { -      /* Advance to the next ARGV-element.  */ - -      if (ordering == PERMUTE) -	{ -	  /* If we have just processed some options following some non-options, -	     exchange them so that the options come first.  */ - -	  if (first_nonopt != last_nonopt && last_nonopt != optind) -	    exchange ((char **) argv); -	  else if (last_nonopt != optind) -	    first_nonopt = optind; - -	  /* Skip any additional non-options -	     and extend the range of non-options previously skipped.  */ - -	  while (optind < argc -		 && (argv[optind][0] != '-' || argv[optind][1] == '\0')) -	    optind++; -	  last_nonopt = optind; -	} - -      /* The special ARGV-element `--' means premature end of options. -	 Skip it like a null option, -	 then exchange with previous non-options as if it were an option, -	 then skip everything else like a non-option.  */ - -      if (optind != argc && !strcmp (argv[optind], "--")) -	{ -	  optind++; - -	  if (first_nonopt != last_nonopt && last_nonopt != optind) -	    exchange ((char **) argv); -	  else if (first_nonopt == last_nonopt) -	    first_nonopt = optind; -	  last_nonopt = argc; - -	  optind = argc; -	} - -      /* If we have done all the ARGV-elements, stop the scan -	 and back over any non-options that we skipped and permuted.  */ - -      if (optind == argc) -	{ -	  /* Set the next-arg-index to point at the non-options -	     that we previously skipped, so the caller will digest them.  */ -	  if (first_nonopt != last_nonopt) -	    optind = first_nonopt; -	  return EOF; -	} - -      /* If we have come to a non-option and did not permute it, -	 either stop the scan or describe it to the caller and pass it by.  */ - -      if ((argv[optind][0] != '-' || argv[optind][1] == '\0')) -	{ -	  if (ordering == REQUIRE_ORDER) -	    return EOF; -	  optarg = argv[optind++]; -	  return 1; -	} - -      /* We have found another option-ARGV-element. -	 Skip the initial punctuation.  */ - -      nextchar = (argv[optind] + 1 -		  + (longopts != NULL && argv[optind][1] == '-')); -    } - -  /* Decode the current option-ARGV-element.  */ - -  /* Check whether the ARGV-element is a long option. - -     If long_only and the ARGV-element has the form "-f", where f is -     a valid short option, don't consider it an abbreviated form of -     a long option that starts with f.
