I appended a tarball with a README explaining how to download the getopt
sources and an example file to experiment with GNU getopt(). 

Unfortunately I only use Linux, so I can't verify if the example works
for MAC and microsoft.  But maybe you or some other person could help
out?

Everything - downloading the sources, building and playing with the
example - should only take some minutes.  

If everything works I could write an example patch for Blender
implementing something like a --hello-world option. If this works fine I
could write more patches porting the option parsing code to GNU getopt()
step by step.

Best wishes, Dietrich

PS: Should I rather send this message to some other group?

Here how to use the tarball from a unix bash shell:

Use some directory for temporary files - in my case:

TMP=/tmp

# make a directory to experiment with getopt:

mkdir ${TMP}/getopt
cd ${TMP}/getopt

# unpack the attached sources:

gunzip getopt-exp.tar.gz 
tar xvf getopt-exp.tar
cd getopt-exp/

# continue as described in the README file

cat README

# --- README ---

* getopt docs

  - http://www.gnu.org/software/libtool/manual/libc/Getopt.html


* usage

# make a directory for the original files and download GNU getopt.{c,h}

mkdir vendor-drop
cd vendor-drop
svn export svn://gcc.gnu.org/svn/gcc/trunk/libiberty/getopt.c
svn export svn://gcc.gnu.org/svn/gcc/trunk/include/getopt.h
cd ..

# make blender versions of getopt.* and patch them for usage with
blender

cp vendor-drop/* .
patch -p0 --ignore-whitespace < blender-getopt.patch

# having a look on the differences between original version and blender
versions
# (only the line '#include "ansidecl.h"' was uncommented...)

diff getopt.h vendor-drop/getopt.h
diff getopt.c vendor-drop/getopt.c

# build getopt-exp
# the Makefile has to be edited for windows and mac...
# please post the result if working :)

make

# get usage information

./getopt-exp --help

# play with GNU getopt()

./getopt-exp \
    one \
    -n --no-arg \
    two \
    -r arg1 --arg-required arg2 -rarg1 --arg-required=arg2 \
    three \
    -o --arg-optional -oarg3 --arg-optional=arg4 \
    four \
    -u --unknown-option \
    five \
    -u --unknown-option \
    six


* fin.
