Hi all,

I have run into a problem. I have a project that compiles under MSVC
7.1 but not on gcc 3.1.

I have an abstract base class called Stack which takes a template
parameter to the stack type. It provides iterators and normal stack
functionality.

I want to maintain multiple stacks (with different template types)
within the program. To manage them, I wanted to use a Stack-derived
stack. So I created a StackStack class which is explicitly designed to
hold stack pointers (boost shared_ptrs of stacks, actually).

The code compiles and runs under MSVC 7.1 (.NET 2003), but fails under
gcc. Can you help explain why and what I should do to fix it?

The error I get is:

/ISR_Project/StackBase/StackStack.h:11: error: syntax error before `>' token

Thanks for your help,
Matt.
