While there was just another discouraging report with regard to floating
point on Alpha today, for dlv (a local AI project) with integer code only
we had a nice performance increase from 1.0.3a to 1.1 on sparc-sun-solaris.

All tests were performed an an Ultra1/143 and while dlv is just a single
binary, the three tests exercise different parts of the system.

   dlv    |  1.0.3   1.1     mainbranch-2weeks-ago
   -------+---------------------------------------
   test1  |  1:06    1:03    1:02
   test2  |  1:30    1:24    1:22
   test3  |  3:19    2:51    2:42

Not that bad...
