Great, now I've got 2 questions:

1.) Are shared libraries compiled with gdc abi compitible with dmd?
(if dmd did support shared libraries)

2.) Is it now possible to load a shared d library into a C program? Will
jut loading the library initialize the runtime or is it necessary to
call some runtime setup functions manually? If the C program loads 2 D
libraries, will those share the gc/runtime?
