Hi all--
I am having a rather confusing problem with namespaces and MSVC++ 4.0.
I  have a header file comprising this code (irrelevant details removed
for space):

#include <list.h>
#include <vector.h>

namespace Laplace {
    struct FElement {
    public:
        FElement(double);
        FElement(int);
        ...
    private:
        ...
    };

    typedef  list<FElement> FRep;

    typedef struct {
        FRep repnum;
        FRep repden;
    } FElement2;

    class Laplxfm2 {
    public:
        ...
    private
        ...
    };

}

// End namespace definitions

using namespace Laplace;

list<FElement> list1;
list<FElement2> list2;

// End of header file

When I try to compile the program that uses this header file, the first
errors I see indicate (explicitly) that symbol FElement2 is not defined
(The template specialization fails), whereas symbol FElement is defined.
What gives??

If memory serves, v4.0 - 4.2 of VC++ had some serious bugs in namespace
handling...  You might try avoiding the using clause and use
list<Laplace::FElement> instead.

I didn't think VC++ 4 even supported namespaces. Wasn't version 5
the first one to include them?
