Update:

Patch 2 isn't complete, I missed the implementation ;) - as I 
didn't get to the obvious linking error yet. :P

--------------------

The linking errors when building the ldc2 library vanish as soon 
as I invoke the linker command-line manually and add the 
LLVMX86Utils.lib. It just doesn't work from within VS by editing 
the project options and building.
Anyway, looks like a bug in the CMake config. Unfortunately, I 
don't speak CMake..
