So far it is only enabled on Linux, as I made the necessary 
adjustments to the druntime module registration code and so on 
while working on shared library support there.

That being said, supporting this should be considerably easier 
for platforms that still use the "old" __Dmodule_ref module 
registration mechanism, as the latter doesn't depend on 
unreferenced symbols in a magic section being kept by the linker. 
I can't think of any issues that would preclude using e.g. the 
equivalent linker option on OS X (-dead_strip) right now, or 
---gc-sections on FreeBSD.

But as with all improvements, this simply depends on somebody to 
sit down and make it happen. Getting the thing to work shouldn't 
be too hard, and I'd be happy to help anyone attempting this if 
any tough issues crop up, but if you are just waiting for me to 
find the time to investigate other platforms, you'll probably be 
in for quite a wait.

Cheers,
David
