On i686 (2x Intel Xeon 2.40GHz) I get "1245323 pure bytes used".
On x86_64 (AMD Athlon 64 3500+) I get "2064768 pure bytes used".

Both have the same gcc (GCC) 3.3.4 (pre 3.3.5 20040809) and both are
running SuSE 9.2.  I updated the sources from CVS just before testing
and sending this mail.

With the current sources on this machine: 1245620 pure bytes used

Bye, Reiner.
