Man, it's really slow compiling!

It took over 3 minutes to compile the same project that compiles 
in 10 seconds with combined compile.

Even after compilation of all the object files it takes 10 
seconds just to recompile 1 file.

There is absolutely no speed up.

Also, I always get

x64\Debug DMD\S.exe not up to date: d:\repos\s\s\x64\debug 
dmd\s.exe older than d:\repos\s\s\$(outdir)\g\d\set.obj

and so it has to build this one obj file every time.
I'm not sure what is going on here set.d is not being changed as 
far as I know.

In any case, unless there is a huge bug in single file 
compilation I don't see it being at all faster than combined 
compile.
