Issue with STL, queues and Stacks

[Frank]

I was wondering if I had to do something special to get the STL with
queues and stacks to work?  I have a program working jut fine under
Solaris compiled with Sun Workshop compiler, but will not compile with
g++. Line it's complaining about is :

queue<myclass> *ptr;

or

std::stack<myclass> *ptr;

I have using namespace std: int he the .h and it still compains with or
with out the std:: I have gcc 2.95.3

Thanks,

Frank
