Unable to compile GtkD on windows

[user]

I tried compiling GtkD, I get the error message:

> rdmd Build.d
Error: more than 32767 symbols in object file


1. How to work around this?

2. Is D still unfriendly to newbies? I am disappoint :-(

Using:
DMD 2.077
GtkD 3.7.1
gtk3-runtime_3.22.24-1, 32bit
