how to solve naming conflicts by using namespace

[ff]

Dear all,
When I use Standard Template Library to develop my program by using an existing tool, I find that the tool package also defined its own list, stack and set class. How can I solve this naming conflicts? I consulted namespace facilities, but didn't figure out how to do it without chaning the tool package...
Thank you for your reply.

Can you be more specific. What do you mean "an existing tool" I find that simply declaring:

using namespace std

below my includes does the trick. Mind you, it's in the MS Visual C++ compiler. It's been awhile since I've used the borland tools.
