Hello!
I am currently migrating a project from BCB5 to BCB6. The following
code compiled just fine under BCB5:
,----[ DataList.h ]
#ifndef DataListH
#define DataListH
#include <classlib/listimp.h>
class TData {
};
class TDataList : public TIListImp<TData> {
};
#endif
`----
BCB6, however, fails with a "member identifier expected" error within
listimp.h (line 239, BCB5 Companion CD version). It is an access
declaration within a template class definition. BCB6 obviously is not
able to find the parent class's member equivalent.
I've already added the necessary compiler defines to make BCB6 use the
RogueWave STL implementation.
Have there been made any changes in the way templates get instatiated?
Any other hints what might cause these errors?

I've been able to create a minimal code snippet that shows the
behaviour:
template <class T> class A
{
public:
void operator delete(void *ptr) {};
};
template <class T> class B: private A<T>
{
public:
A<T>::operator delete;
};
class C : B<void>
{
};
Above code compiles under BCB5, but not under BCB6. The latter one
complains about "operator delete" not being a member of A<T>. Has the
nomenclature been changed?

When I use the command line compiler (version 5.6.4) I get the following error message: D:\User\CG\Spielwiese\Builder6\OWL-Test>bcc32 -c DataList.cpp Borland C++ 5.6.4 for Win32 Copyright (c) 1993, 2002 Borland DataList.cpp: Assertion failed DataList.h(17) : type->t.td.tdEnclType->tpTopType == T_TMPLDEP at d:\helena\bcc\indep\template.c(8242) Line 17 of DataList.h is A<T>::operator delete; Any ideas?
