Shared library support

[John Colvin via digitalmars-d-ldc]

What is the state of shared library support across the different 
platforms that LDC supports? What is supposed to work currently 
and what is not?

I seem to be in a perennial state of "try it and see" with this, 
but that makes it hard to tell the difference between expected 
failures (not implemented yet), unexpected failures (something's 
broken) and user error. It would be really great if someone who 
really understand it could give me an overview :)
