error C2678 error with structure, not object?

hi,

when I try to compile with MSVC Version 8, I get the following error:

============
1>C:\Program Files\Microsoft Visual Studio 8\VC\atlmfc\include
\afxtempl.h(161) : error C2678: binary '==' : no operator found which
takes a left-hand operand of type 'const Taboo' (or there is no
acceptable conversion)

========

What's confusing about this is that Taboo is a structure, not an
object. I don't see why it's complaining that it can't find a '=='
operator when Taboo is not even an object.

The source code follows below:

any help appreciated.
