Are the *.di generated automatically, or are they written by 
hand? The compiler is known [0] to have problems with header 
(*.di) generation, and IIRC there were some fixes recently [1] 
that may have caused this problem. On the other hand there are no 
known issues with importing *.di, since it works the same as as 
improting plain *.d files (*.di is only a convention - you can 
functions without bodies or vice versa in both).

Looking at https://pastebin.com/UgWNqZzh it seems that the 
problem shouldn't be hard to solve, since it's only a syntax 
error. I suggest examining and manually editing 
../dwt/imp/org/eclipse/swt/accessibility/Accessible.di to narrow 
down the problem.

I have no knowledge of DWT, so sorry if this is not very helpful.
