Building GtkD app on Win32 results in 111 MiB file mostly from zeroes (compressed size - 324 KiB)

[Denis Shelomovskij]

AFAIK GtkD is the only mature crossplatform GUI for D. So the question 
is: 111 MiB *.exe file mostly from zeroes is good/acceptable? Is it a 
bug or it's how dmd2+OPTLINK works? It looks like dmd1 hasn't this issue.

Files (dmd 2.054 compiled) are here:
