+/*
+	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:
+		http://sourceforge.net/projects/flac
+
+	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.

+   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.  */

+   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

+   arguments to the option '\0'.  This behavior is specific to the GNU
