  	NOTE:
  	I cannot get the vanilla getopt code to work (i.e. compile only what
  	is needed and not duplicate symbols found in the standard library)
  	on all the platforms that FLAC supports.  In particular the gating
  	of code with the ELIDE_CODE #define is not accurate enough on systems
  	that are POSIX but not glibc.  If someone has a patch that works on
  	GNU/Linux, Darwin, AND Solaris please submit it on the project page:
  		https://sourceforge.net/p/flac/patches/
  
  	In the meantime I have munged the global symbols and removed gates
  	around code, while at the same time trying to touch the original as
  	little as possible.

  /* Describe the long-named options requested by the application.
     The LONG_OPTIONS argument to share__getopt_long or share__getopt_long_only is a vector
     of `struct share__option' terminated by an element containing a name which is
     zero.
  
     The field `has_arg' is:
     share__no_argument		(or 0) if the option does not take an argument,
     share__required_argument	(or 1) if the option requires an argument,
     share__optional_argument 	(or 2) if the option takes an optional argument.
  
     If the field `flag' is not NULL, it points to a variable that is set
     to the value given in the field `val' when the option is found, but
     left unchanged if the option is not found.
  
     To have a long-named option do something other than set an `int' to
     a compiled-in constant, such as set a value from `share__optarg', set the
     option's `flag' field to zero and its `val' field to a nonzero
     value (the equivalent single-letter option character, if there is
     one).  For long options that have a zero `flag' field, `share__getopt'
     returns the contents of the `val' field.  */

     options given in OPTS.
  
     Return the option character from OPTS just read.  Return -1 when
     there are no more options.  For unrecognized options, or options
     missing arguments, `share__optopt' is set to the option letter, and '?' is
     returned.
  
     The OPTS string is a list of characters which are recognized option
     letters, optionally followed by colons, specifying that that letter
     takes an argument, to be placed in `share__optarg'.
  
     If a letter in OPTS is followed by two colons, its argument is
     optional.  This behavior is specific to the GNU `share__getopt'.
  
     The argument `--' causes premature termination of argument
     scanning, explicitly telling `share__getopt' that there are no more
     options.
  
     If OPTS begins with `--', then non-option arguments are treated as
     arguments to the option '\0'.  This behavior is specific to the GNU
     `share__getopt'.  */
