An example:

GtkD is built using singe (gtk-one-obj.lib) or separate (one per source 
file) object files (gtk-sep-obj.lib).

Than main.d that imports gtk.Main is built using those libraries.

Than zeroCount utils is built and launched over resulting files:
--------------------------------------------------
   Zero bytes|     %|    Non-zero| Total bytes|        File
      3628311| 21.56|    13202153|    16830464|gtk-one-obj.lib
      1953124| 15.98|    10272924|    12226048|gtk-sep-obj.lib
    127968798| 99.00|     1298430|   129267228|main-one-obj.exe
       743821| 37.51|     1239183|     1983004|main-sep-obj.exe
--------------------------------------------------

These zero byte counts are similar for dmd 2.054-2.057.

So one has to use very slow per-file build to produce a good (not 100 
MiB) executable.
No matter what *.exe is launched, its process allocates ~20 MiB of RAM 
(loaded Gtk dll-s).
