Glad it was helpful! :-)

Eeeeeeeh... *technically* it isn't wrong (you can mix -W, -f options,
for example) but I see why it confused you, and I agree that it *really*
ought to say something about -l being in the 'order can matter'
category. You are by no means the first person on Windows to get bitten
by this.
To whoever maintains the doc: we really should add something like "Note
that the order of objects, including libraries specified by -l, DOES
matter on some platforms.", perhaps with an even longer explanation as
well such as what was in my previous post.
