Yes,  of  course,  I  meant MINUTES and not seconds...  Where have I put my
brain?   :-)
But  Lattice  makes  really  only up to 800 lines/min(now I got it) and not
2000.   (And  this  of  course only if you don't use the optimizer.).  I've
tested  it  with several source code lengths, and I came not over 800.  How
do you get this high performance?
