Sure, one way to go about this would be to just sit down and implement a common ABI in GDC and LDC (hackathon at London/Zürich/… anyone?) and then hope that some random contributor turns up later on and fixes DMD to conform to the standard we agreed on. But this does not necessarily strike me as a productive gamble…
You could always go the other way and change GDC and LDC to match what DMD does. :)
