I'm porting an older VS 6 C++ application to NET 2003 and
getting a C4702 (unreachable code) warning at /W4 for the
following code:

throw new CArchiveException( CArchiveException::none,
User.GetName());

where User.GetName() is a function returning a CString.

The following code does *not* produce the warning:

CString  Name = User.GetName();
throw new CArchiveException( CArchiveException::none,
Name );

It looks to me like this is a bogus warning.  Is it?  Can
it be fixed?
