DMD is Boost licensed meaning yes, you can include it.

For GDC, it's GPL licensed. LDC is Apache licensed. I'm not sure how that would apply to your app's license.

Awesome.  Thank you!  Is there any reason I should switch to GDC or LDC?  It would be nice to have the speediest compilation time, for small-to-medium sized user codes + library usage, but the library won't change usually.

They each have their own strengths and weaknesses. You'll need to evaluate that in the context of your requirements.
