Patch for wrong no declaration seen for command-line-arguments

[Matthieu Vachon <matthieu dot o dot vachon at gmail dot com>]

Hi Per,

Here my try at fixing the incorrect warning that occurs when
generating a main method and using the `command-line-arguments`. It's
probably not the optimal way to fix the issue but I hope it is good
enough to be included in the trunk.

I added two test cases but I'm unsure if the syntax I used is right.
Talking about that, what is the procedure to run the test suite? I
would like to know so I can test my patches when developing them prior
to sending them to you.

Regards,
Matt
