D slower than C++ in compile time

In addition ...
This does not mean it should be equal compile time. dwt uses tango, so 
its about double size of types/declarations for the compiler. So i 
wonder how it grows if you build an application on top of dwt with 
another 300 files :)

I gave it a try to measure both times for linux to compile dwt
dmd options: -g -gc -debug -v
dsss options: -full -v
2.8Ghz 2GB Ram

oneatatime=off :  0:31
oneatatime=on  : 31:49

I would reason, with oneatatime=off we see here a much stronger effect 
of more RAM size and CPU speed. With oneatatime=on the file I/O has much 
more weigth, so here the difference is not so big.
