SYMPTOMS
========
When encountering a cast to a structure pointer in the default argument of a
class member function, the Visual C++ compiler generates the following error:
error C2371: 'MyClass' : redefinition; different basic types
This error does not occur if the function declaration is not a member of a class.
RESOLUTION
==========
If you are casting from an integral literal, remove the cast. For example,
change this:
MyFunc (struct MyStruct *p = (struct MyStruct*)0); //C2371 error
to this:
MyFunc (struct MyStruct *p = 0); //no error
If you are casting from a different structure type, remove the struct keyword
from the cast. For example, change this:
yFunc (struct MyStruct *p = (struct MyStruct*)x); //C2371 error
to this:
MyFunc (struct MyStruct *p = (MyStruct*)x); //no error
STATUS
======
Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This bug was corrected in Visual C++ version 5.0.
