I have noticed that the size of my code has been growing
at an alarming rate recently. After some investigation, I
discovered that it is due to multiple copies of virtual tables.

It seems that each object file that accesses a class, ends up
with a copy of that class' virtual table. I one case, I counted 
91 object files that contain a copy of the same virtual table.

The virtual tables are taking up something like 25% of my code.

Please tell me that there is a way around this, that my code size
is not going to expand exponentially.

I am using gcc v2.6.0.



Thanks for any help
