           Summary: c++ parser error
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: critical

         Component: c++

The g++-3.3 parser fails to parse the code bellow with the following error message: 
test.cc:33: error: declaration of `Bitmap::operator GdkBitmap*() const' 
test.cc:23: error: conflicts with previous declaration `Bitmap::operator 
   GdkBitmap*() const' 
 
This code compiles cleanly with g++-3.2. Some changes to the code, e.g. move the  
class Event to the end of the file, makes the file to compile cleanly with g++-3.3. 
 
The problem also exists in current HEAD.
