preprocessed source

Command line for gcc:
/usr/local/gcc40d/bin/g++40d -O2 -g -march=opteron
 -Wall -DALTIVEC -DUSEACE -c
 -o ../../../../LinuxExec/arrilib/ArriutilTest.o
 ../../../Portabel/arrilib/compile/ArriutilTest.cpp
 -I../../../Portabel/arrilib
 -isystem/home/cie019/ace542-gcc40/ACE_wrappers
 -DHAVE_ACE_NULL_MUTEX_H -isystem/usr/local/cppunit-gcc40/include
 -I../../../../include/arrilib

Output from gcc:
/usr/local/cppunit-gcc40/include/cppunit/extensions/TestFixtureFactory.h:
 In instantiation of 'CppUnit::ConcretTestFixtureFactoryArriutilTest':
../../../Portabel/arrilib/compile/ArriutilTest.h:32:   instantiated from here
/usr/local/cppunit-gcc40/include/cppunit/extensions/TestFixtureFactory.h:30:
warning: 'class CppUnit::ConcretTestFixtureFactoryArriutilTest' has virtual
functions but non-virtual destructor

This gcc was snapshot 20050213, but 20050220 makes no difference.

I cannot reproduce this with 4.0 (20050222).
tin:~/src/gnu/gcctest/pr20145cat include/t.h
class t
{
  virtual void f();
};
tin:~/src/gnu/gcctest/pr20145cat t.cc
#include t.h

class t1
{
  virtual void f();
};

void f(void)
{
  t h;
  t1 h1;
}

tin:~/src/gnu/gcctest/pr20145gcc t.cc -isystem include/ -W -Wall -S
t.cc:4: warning: ‘class t1’ has virtual functions but non-virtual destructor

Can you include the preprocessed source (the preprocessed source will have the 
thing if a header is a 
system header or not)?
