No, there isn't such rule. DRuntime OS dependent code is 
currently chaotic. I posted previously that I wanted an API for 
the OS dependent stuff and OS dependent code must be in their own 
files.

No, it isn't.

I think we should use a generic version as much possible. This 
means that each OS can have it's own dlfcn.d file but if POSIX 
can be used this file should include the generic POSIX dlfcn.d 
file.

We can have multiple dlfcn.d files but implementation should be 
moved to the generic one as much as possible.
