/*
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 remove 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 FLAC__share__getopt_long or FLAC__share__getopt_long_only is a vector
of `struct FLAC__share__option' terminated by an element containing a name which is
zero.
The field `has_arg' is:
FLAC__share__no_argument (or 0) if the option does not take an argument,
FLAC__share__required_argument (or 1) if the option requires an argument,
FLAC__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 `FLAC__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, `FLAC__share__getopt'
returns the contents of the `val' field. */

Return the option character from OPTS just read. Return -1 when
there are no more options. For unrecognized options, or options
missing arguments, `FLAC__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 `FLAC__share__optarg'.
If a letter in OPTS is followed by two colons, its argument is
optional. This behavior is specific to the GNU `FLAC__share__getopt'.
The argument `--' causes premature termination of argument
scanning, explicitly telling `FLAC__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
`FLAC__share__getopt'. */
