I don't see a need to compile OSX executables from Windows, Linux or FreeBSD. I 
don't recall it ever coming up.

DMD is not currently set up to cross compile that way, because the object file 
and library file code is a compile time switch. Making O-C a run time switch 
would still not make it a cross compiler.

The stub file is still pointless extra complexity, though, and using a compile 
time version will enable it to be merged with the non-stub file. It'd be a nice 
improvement.
