State of interfacing with c++

[Jonas Drewsen via Digitalmars-d]

For a hack week at work I am thinking about creating a module in 
D that can be used with our existing application which is written 
in C++.

Can anyone shed some light on the current status of interfacing 
with C++? In particular:

1, Can I build my C++ program using visual c++ and then link a D 
module compiled with gdc/ldc/dmd into it using the ms linker?

2, Can I do the same with the OSX tool chain ie. compile main 
program using xcode clang etc.

3, And what about linux?

3, Which features of D or C++ should I expect not to work or 
shouldn't use when interfacing.

Any pointers to reasonably up-to-date info about interfacing with 
c++ is much appreciated as well.

Thanks
