extern(System) should be fine in that it's the same as extern(Windows) on 
Windows, but since it's a Windows-specific function, it probably _should_  be 
using extern(Windows).

Of course, since PathRenameExtensions does what std.path.setExtension does, it 
would probably be better to just use that, but the OP's question _does_ apply 
to other functions which may not have D replacements, so the question is still 
relevant.
