I think you need to replace mingw/include/d/3.4.5/object.d with your  
version.  So backup the one there, replace it with yours, and see what  
happens.

GDC has a "weird" directory structure for the intrinsic imports.  I'm not  
sure if that's the fault of the D implementation or the phobos library  
mechanics hard-wired into D :(. I actually wish the structure were dirt  
simple for those dmd/gdc users who want to create there own kernels. Right  
now, it seems to require a certain amount of hackery to get around the  
setup.

At the very least, we'll eventually need a tutorial for how to  
roll-your-own phobos-replacement and attach it to d.  Ares is a good  
example of a start, but I believe it is dmd only, at this point.
