I wrote a reply to this but amn't sure what happened it, using a new
news reader :-(

I am using the default library (i.e. VC98\Include)
One thing I noticed is that when I "Go to definition" in the project
that works it takes me to <typeinfo> as expected
in the projects that don't work it takes me to <typeinfo.h> which
doesn't have the namespace

I don't know what the cause of the confusion is though
there are no includes for <typeinfo.h> in my code but this is a Com
and MFC project so there are a lot of includes lying around
Even if it was included I can't see why there would be a problem
