Hey  it is a WARNING...
/* ... */ comments do not nest!
So just change the M$ include file (mapi.h) and solve the problem that 
way if it is that important to you.

Being wxWidgets developer responsible for delivering wxWidgets in warning 
free form under all free compilers I care about quality delivered to the 
users. I can't change mapi.h in user's instalations. I do not care for such 
a warning for myself.

I can understand that, but that warning is not something we control.
Just add a release note that if the users want this warning to disappear 
to change this particular line in the M$ header file (mapi.h).
You also might want to report it to M$.

But timestamps suggests that about 10 files in win32 were already modified 
after 1996 year (which can be easily verified comparing latest beta with 
dm81dc.zip ftp).

I use one of the much later M$ SDK's and have to make changes to header 
files to prevent these warnings. I know there are others out there that 
also use more recent SDK's...

Using the dmc switch:

Dear Walter,

Thanks for a new version of compiler!

Please check following code, it looks like a compiler bug:

//--- "nested_friend.cpp":

class C
{
public:
C() {};
};

class A: public C
{
private:
class B: public C
{
protected:
friend class A;
A* m_pThis;

public:
B( A & a ): m_pThis(&a) {}
int IncCnt() { return ++( m_pThis->m_Counter ); }
int DecCnt() { return --( m_pThis->m_Counter ); }
};

public:
A(): m_Counter(0) {}

protected:
friend class B;
int m_Counter;

private:

};

//--- eof "nested_friend.cpp"

Compilation result:

dmc -v -c nested_friend.cpp
scppn -Aa- -6 -v nested_friend.cpp

Dear Walter,

Please check following example, it causes run-time error in debug version
when linked under DMC 8.40 with SNND.lib. I have prepared it as console
application, but similar error appear in MFC GUI application (which works fine
with version 8.37).

//--- "dbg_heap.cpp":
#include <stdio.h>
#define _CRTDBG_MAP_ALLOC 1
#include <crtdbg.h>

template<class TYPE>
class TArray
{
TYPE    * m_pBuf;

unsigned long   m_Size;
unsigned long   m_PgSize;

public:

TArray( unsigned long nInitSize = 0, unsigned long nPgSize = 16 );
~TArray();

void  Allocate( unsigned long nSize );
void  Free();
};

template <class TYPE>
void TArray<TYPE>::Free()
{
if ( m_Size > 0 )
{
delete [] m_pBuf;
//^^^^^^^^^^^^^ *** Error here!
m_Size = 0;
}
};

template <class TYPE>
void TArray<TYPE>::Allocate( unsigned long nSize )
{
if ( nSize > 0 )
{
m_pBuf = new TYPE [nSize];
m_Size = nSize;
}
};

template <class TYPE>
TArray<TYPE>::TArray( unsigned long nInitSize,
unsigned long nPgSize )
{
if ( nPgSize < 16 )
{
nPgSize = 16;
}
m_PgSize = nPgSize;
if ( nInitSize == 0 )
{
m_pBuf = NULL;
m_Size = 0;
}
else
{
Allocate( nInitSize );
}
};

template <class TYPE>
TArray<TYPE>::~TArray()
{
Free();
};


typedef struct tree_item
{
void * ti;

tree_item();

} tree_item_t;

tree_item::tree_item() : ti(NULL)
{
}

typedef TArray<tree_item_t> TTreeItemArray_t;



void test( void )
{
TTreeItemArray_t hChildItems( 64, 64 );

}

int main()
{
_CrtSetReportMode( _CRT_WARN, _CRTDBG_MODE_FILE );
_CrtSetReportFile( _CRT_WARN, _CRTDBG_FILE_STDOUT );
_CrtSetReportMode( _CRT_ERROR, _CRTDBG_MODE_FILE );
_CrtSetReportFile( _CRT_ERROR, _CRTDBG_FILE_STDOUT );
_CrtSetReportMode( _CRT_ASSERT, _CRTDBG_MODE_FILE );
_CrtSetReportFile( _CRT_ASSERT, _CRTDBG_FILE_STDOUT );

printf( "test()\n" );
test();
printf( "done...\n" );

_CrtDumpMemoryLeaks();
}

//--- eof "dbg_heap.cpp"

The example has been compiled with following flags:

dmc -cpp -Ae -r -mn -C -WA -S -a8 -gh -D_DEBUG=1 -NLsnnd dbg_heap.cpp


Thanks in advance.

Dear Walter,

(Sorry, it's me again...)

Possibly a bug: 

The DMC version 8.40 does not embed to .obj-file includelib statements from
precompiled headers. 

Thanks in advance,

Sergey Gutnikov
