New: gengetopt 2.23

[Cygwin gengetopt co-Maintainer]

Generates a function to parse and validate command line options.

The missing x86 package has now been added to the Cygwin distribution. 

The following package has been added to the Cygwin distribution:

* gengetopt	2.23

Reads an interface description file, and writes a file containing a
command-line parser function.
Generates a C function that calls the getopt_long function to parse
command line options, to validate them, fill a struct, or output a
usage message.
Can also generate functions to save command line options into an rc
file, and to read command line options from an rc file.
Handles long options starting with '--' and short options starting with
'-' followed by one character, without parameters and with 11 types of
parameters (including flag, int, double, string, and function call)."

Version 2.23

* Gengen and gengetopt are required when building from git.
  When building from tarball, everything works like it did before.
* To mimic behaviour of coreutils, version string is no longer part of
  --help, and usage is printed before purpose in --help
* Use singular (`[OPTION]...`, `[FILE]...`) instead of plural
  (`[OPTIONS]...`, `[FILES]...`)
* Fix spelling of `--unnamed`. `--unamed` still provided for backwards
  compatibility.
* Drop IRIX compatibility
