licensing confusion :(

[dcoder via Digitalmars-d]

I am not sure if this is the right place to be posting a question
on licensing, but hopefully so...

I wonder if someone can explain the implications of using the dmd
compiler which has (if my understanding is correct) a proprietary
backend; how might this affect the commercial distribution of a
project?

So far the most concise explanation that I have been able to find
is from a blog post from almost two years ago entitled
'Dispelling Common D Myths':

Unfortunately, this is still not clear enough for me, and also
not very reassuring.

If I compile a project down to an executable by way of dmd, then
would I need permission to distribute that executable as a
commercial project?
