Confusing errormessage with implicit typename

[Nicolas Pavlidis]

Hi!

This is my first posting to the list, if I made something wrong please
tell me!

Here's my problem:
Look at this peace of code:

----------8<-------------------snapp------------------------>8----------
typedef std::map<IdentifierType, ObjectCreator> CreationCallbackMap;
typedef CreationCallbackMap::iterator CreationCallbackMapIter; 
   // ^^^^^ Here the keyword 'typename' is missing
----------8<-------------------snipp------------------------>8----------

gcc 3.4.1 told me the following:

----------8<-------------------snapp------------------------>8----------
/home/pavnic/projects/converter/src/utilities/factory.h:151: error: type
`std::map<IdentifierType, ObjectCreator, std::less<IdentifierType>,
std::allocator<std::pair<const IdentifierType, ObjectCreator> > >' is
not derived from type
`Crazy_::Utilities_::ObjectFactory<AbstractProduct, ObjectCreator,
IdentifierType>' 
----------8<-------------------snipp------------------------>8----------

After a diskusion on usenet I found out that gcc 3.2 produces a more
readable message, though it's "only" a warning. Here is it:

----------8<-------------------snapp------------------------>8----------
/home/pavnic/projects/converter/src/utilities/factory.h:151: warning:
`typename  
   std::map<IdentifierType, ObjectCreator, std::less<IdentifierType>, 
   std::allocator<std::pair<const IdentifierType, ObjectCreator> >
>::iterator'  
   is implicitly a typename
/home/pavnic/projects/converter/src/utilities/factory.h:151: warning:
implicit typename is deprecated, please see the documentation for
details 
----------8<-------------------snipp------------------------>8----------

I don't know if there are other examples where errormessages got a
little bit wors in the 3.4x relaase. Maybe it is possible to make gcc
producing more readable errormessases.

Best regards,
Nicolas

P.S. I don't know how difficult it is to change such things, so please
don;t flame me :-)!
