[Boost-users] declaration does not declare anything - exception

Hi,

When I compile with Xcode I get a 'declaration does not declare 
anything' error on boost/exception/diagnostic_information.hpp.

However, the exception test run fine when I compile with bjam 
--toolset=darwin ...

I am quite sure both use the same compiler (g++-4.0.1) and have the same 
options (I copied from the bjam set to Xcode).

I now outcommented it (see below), but this is not a permanent solution. 
It should be valid, so what am I doing wrong regarding Xcode?

Any help would be very much appreciated!

Best, Dirk
