RE: [Boost-Users] bind: I just keep trying...

<datapoints>
MSDN January 2002 contains only the 'old' level 1 definition.
Q113417 from that same source says the compiler generates the warning with
both the /Ze and /Za switches.
The 'online' MSDN contains only the level 3 definition.
You're running SP3 and I'm running SP5.

THEREFORE:

#pragma warning(disable : 4097)     // ;)
#include <boost/function.hpp>
#pragma warning(default : 4097)

Thanks for the input.

According to the MSDN:

---------------- begin quote from MSDN -----------------------------
Compiler Warning (level 3) C4097

typedef-name 'identifier1' used as synonym for class-name 'identifier2'

A typedef name which names a class is itself a class name. However, only a
class declared without a tag can be named. In the following line of code
the
typedef name P is promoted to class name but Q is not.

typedef struct { int member; } P, Q;

Q remains a normal typedef name and a synonym for the class.

The following example causes this warning:

typedef struct _T
{
    int i;
} T;

struct U : T
{
    int j;
};               // warning

struct V : _T
{
    int j;
};               // OK

------------------------ end quote from MSDN -------------------------

However, when I tried compiling the example, MSVC6 SP3 at warning level 4
was completely silent. So I'm really confused now - is it a problem or not?
My instinct says no, but I've been wrong before.
