[GtkD] Error 1: Previous Definition Different : __Dmain

[Adrien Tétar" <adri-from-59 at hotmail.fr>]

Hi,

I have compiled GtkD 2.0 on Windows. Source files are passed to 
the compiler as well as library to the linker.
I followed instructions from here : 
https://github.com/gtkd-developers/GtkD/wiki/Installing-on-Windows

But there is an error appearing when GtkD.lib is passed to the 
linker:
Error 1: Previous Definition Different : __Dmain

This is supposed to mean that there are two main function in the 
code, but how do I fix it ?

Thanks in advance.

PS: I use DMD 2.060.
