LDC has its own forks of druntime and Phobos, with numerous 
required adaptations. So you'd need to apply your patches to 
those forks & build the libs (druntime and Phobos are separate 
libs for LDC), e.g., with the included ldc-build-runtime tool, 
which makes this painless:

The Wiki page also shows how to link those libs instead of the 
shipped-with ones.
