Seeing as I was the one who sparked off this sub-thread I should respond 
at this point. The definition of reverse-engineering that I was using 
is the same one Alexandre used - somehow (by various possible methods) 
figuring out how an engineered product works or what it does, then 
making a new and different product to do the same thing. Implied is the 
factor that this new thing is not a direct copy of the original - that 
would be a facsimile, duplicate or copy which Wine definitely isn't.

There could be many definitions of reverse-engineering and we could 
debate semantic consequences of no consequence for hours. But this here 
list isn't slashdot so I don't want to go there :-)

At least most of us here know what Wine is, how it works and have a good 
idea of how it was developed
