** Parse the command-line arguments passed to windows.  We do this

** Parse the Windows command line string into argc/argv. Done here
** because we don't trust the builtin argument parser in crt0. Windows
** applications are responsible for breaking their command line into
** arguments.
**
** 2N backslashes + quote -> N backslashes + begin quoted string
** 2N + 1 backslashes + quote -> literal
** N backslashes + non-quote -> literal
** quote + quote in a quoted string -> single quote
** quote + quote not in quoted string -> empty string
** quote -> begin quoted string

** Results:
** Fills argcPtr with the number of arguments and argvPtr with the array
