           Summary: Compiler cannot find user defined implicit typecast
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: jan at planet dot de
                CC: gcc-bugs at gcc dot gnu dot org

GCC 3.3 does not find the user defined typcast in the appended code. In gcc 2.95.3 
and Borland C++ 6 it does work. 
 
Compiling with "g++ bugsim2.cc" failes with:
