I agree on this data point, but the discussion was long range compile
There are many days in the past where compile
time increase for a few days and then the problem is fixed
(which is hopefully likely to happen here to).
One thing to note is that Diego machine is a Pentium4 which is
very sensitive to small changes in code generation (much more than
Pentium 3 or Athlon), it might be better to build the daily GCC with
-mcpu=pentium4 on such machines.
