Yep, checked that. Even checked the .exp file and compared the
mangled name there with the mangled name that D tries to use,
they are the same. I know someone who worked on improving DLL
support for D a while back and he said he had to fix this in D
but didn't get that merged into DMD back then (since there were
many other things as well) and now he doesn't have time to work
on it further :(
