What I should have written is:

Windows programs receive a single string of arguments to parse whereas
Unix programs receive an array which can be passed to main unchanged by
the startup code.
...
A full solution will need to be a little bit more complicated.  There
isn't a specification of how Windows command-lines should be converted
to or from an array of strings...

By the way, the startup code or other command-line parser does not
have to handle redirection or variable substitution; this *is* done by
the command processor (which implies that it does parse the command-
line, even though it doesn't give you the results of this).
