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.
