Yup I am.  I'm not sure what you are saying you modified your sc.ini 
from though.  Are you refering to the -L+tango-user-dmd.lib part?

This seems like an issue that needs attention to me.

I'm using dsss mostly so I can't put that -L+tango-user-dmd part in my 
sc.ini.  That's because dsss puts those functions in libraries called 
something else and links with them automatically.  So adding the -L 
would create lots of multiply defined stuff when I build with dsss.

But I don't always use dsss.  Especially not for small things.  But that 
means when I compile small things I have to add tango-user-dmd.lib to 
the compile line explicitly, which is annoying.  It's part of the 
(alternative) standard library, I shouldn't have to specify it explicitly.

I'm not sure what needs to change to make this annoying dilemma go away. 
  Seems like it would have to be something in DMD itself, unfortunately.

I agree that DSSS is far from perfect.  I think Gregor's biggest mistake 
was to assume that handling D dependencies perfectly would solve all 
build problems (or at least he seems to have made that assumption).  But 
it's just not the case.  In real software there are all kinds of 
dependencies that come from all kinds of places.  A build tool that does 
not have a general dependency engine is a cripple from the outset.

Too bad Gregor has mostly disappeared these days, or maybe DSSS would 
already have such a dependency engine.
