   particular, this is why we define a struct and not an object (which would
   result in a warning about unused variable) and a named struct (otherwise we'd
   get a warning about an unnamed struct not used to define an object!).
-  The _n__ part is to stop VC++ 7 being confused since it encloses __LINE++ in
-  parentheses. Unfortunately this does not work with other compilers, so
-  we will only enable it when we know the _precise_ symbols to test for.
