Afaik druntime does not support: iOS, Windows Metro, Windows RT(ARM).
GDC is only a frontend for gcc, so if you do some magic you might be able to get D to work on any platform that gcc can support. But only if you manage to get the d runtime running on that platform.
I know that someone managed to get gdc to work with android and partly ported druntime over to android.
For consoles I don't really know, but I think that it will be rader hard to get it working there.
