LDC is doing a full link each time, while with incremental linking you 
can get this far lower (like dmd is doing), which is not accurate 
unfortunately. If you did use incremental linking you unfortunately must 
remove the extra unused import libraries that LDC is adding (which don't 
make enough of a difference to matter with a full link.

TLDR: LDC is correct, DMD is giving not entirely correct results. But 
there should be some wins here if different choices were made.
