+ 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. */

+
+ The OPTS string is a list of characters which are recognized option
+ letters, optionally followed by colons, specifying that that letter
