Porting code to Linux, need guidance

[Kenton Groombridge]

Hi,

Hopefully this is the right group for this.  I am working on getting 
Alien vs Predator completely ported to Linux.  I am using the code that 
is available from icculus.org.

I recently upgraded my gcc to 3.4.1 and now a portion of the code 
doesn't compile.

I think I figured it out, but want to be sure before I spend a bunch of 
time working around it only to find that I was wrong.

My guess is the class ConstIterator makes class Iterator a friend, but 
class Iterator is a derived class of the bass class ConstIterator (hope 
I said that right).  From what I understand and have researched is that 
 in order for the class ConstIterator to use the class Iterator as a 
friend, then class Iterator has to be defined first, and for class 
Iterator to be derived from class ConstIterator, then the class 
ConstIterator has to be defined first.  Essentially a catch 22.

Am I on the right track?  If so I would like to fix the code, but I 
would like to know how you would approach the fix for this.

Thanks,
Ken
