For ldc it looks like there's about a 5 second difference (I don't have 
exact timings), so it does save some time, not a huge amount though.

With dmd it makes an even bigger difference, the previous time of 6.9 
seconds looks huge in comparison. Passing all files at once to dmd 
causes the compilation time to be but down to about 1.7 seconds! That's 
340k LoC in 1.7 seconds... I'm in awe :D
