Right, it's even faster for me on Linux. Keep in mind, though, that LLVM 
is usually a "build once, then link to/use" thing. Building LDC itself 
is just building DMD + the glue layer (excluding druntime and phobos), 
which is relatively fast.


By the way, is it planned that DMD will be able to use Microsoft's 
linker when compiling with COFF? Or is it too early to say at this 
point? (It would simplify a lot of things; particularly, integration 
with MSVC projects. Further, Optlink's command line is really unfriendly 
and hard to integrate in most build systems.)
