That isn't the only option I'd like to enforce. :-)

Merry Christmas David, you were really awesome and helpful this year. I
certainly hope that I can gain access to that HPUX server of yours again
in the new year and finish off GCC 4.3.4 as a reasonable package.  Maybe
now that it is colder you will have a reason to leave it running longer
and generate heat :-)
