That's why I said I don't include the .h file
if it is included it is done somewhere I can't find

I tried creating clean projects using the VC6 Wizards and none of them
have a problem, so I am stumped

One thing I did notice is that VC7.1 compiles the same code perfectly
which it shouldn't do if it is a problem with my code.
I assume there have been changes between in the libraries in VC6 and
VC7 which stop this from happening

So it would appear to be an interdependency in VC6 libraries but I
can't figure out what is causing the clash or how to fix it

I can, of course, work around it by putting
namespace std { using ::type_info; }
before the include but that seems a bit nasty !
