I think if you pass your source directories via -I the order that *.d 
get compiled doesn't matter (beyond efficiency ..).

Haven't used gdc in a long time though.

As far as dependencies, yeah, a d file will be dependent on anything it 
imports. In DMD there's a -deps flag that outputs that information, and 
in verbose mode, it will print out any import that it processes. I don't 
know how much of that gdc has.

But I really think you shouldn't do that anyways.
