Bug#203351: g++-3.3: Broken parser

[Goedson Teixeira Paixao <goedson@debian.org>]

Package: g++-3.3
Version: 1:3.3.1-0rc1
Severity: important

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 gcc-snapshot.
