compiled code file size

[Duke Normandin]

I'm re-visiting the D language. I've compared the file sizes of 2 
executables - 1 is compiled C code using gcc; the other is D code 
using dmd.

helloWorld.d => helloWorld.exe = 146,972 bytes
ex1hello.c => ex1-hello.exe = 5,661 bytes
Why such a huge difference???
