OS          : Linux Ubuntu 7.10
Compiler    : DMD 1.026
Runtime     : Tango SVN trunk rev. 3188
DSSS        : 0.75

Note: DSSS has by default the feature active to compile one file a time.
For DWT this make compilation _very_ slow (> 10 min).
By switching this off, and make it compile several files at once, the
compile time decreases to <15sec on my machine.
