Adapt lyxpak.py to work with Python 3 on Windows
Seemingly, the elements of argv on Windows are a different type with respect to Linux. A patched version of getopt.py has to be used on Windows in order to match variable types.

"""Parser for command line options.
|

|

This module helps scripts to parse the command line arguments in
|
||||
sys.argv. It supports the same conventions as the Unix getopt()
|
||||
function (including the special meanings of arguments of the form `-'
|
||||
and `--'). Long options similar to those supported by GNU software
|
||||
may be used as well via an optional third argument. This module
|
||||
provides two functions and an exception:
|
||||
|
||||
getopt() -- Parse command line options
|
||||
gnu_getopt() -- Like getopt(), but allow option and non-option arguments
|
||||
to be intermixed.
|
||||
GetoptError -- exception (class) raised with 'opt' attribute, which is the
|
||||
option involved with the exception.

colon (i.e., the same format that Unix getopt() uses). If

'-x'), and the option argument as its second element, or an empty
