Free the DMD backend

[default0 via Digitalmars-d]

I have no idea how licensing would work in that regard but 
considering that DMDs backend is actively maintained and may 
eventually even be ported to D, wouldn't it at some point differ 
enough from Symantecs "original" backend to simply call the DMD 
backend its own thing?

Or are all the changes to the DMD backend simply changes to 
Symantecs backend period?

Then again even if that'd legally be fine after some point, 
someone would have to make the judgement call and that seems like 
a potentially large legal risk, so I guess even if it'd work that 
way it would be an unrealistic step.
