=========================

I have got a problem with compilation of the following piece of code
  using Digital Mars C/C++ compiler.

There was no problem with this code while using GNU g++ 3.2.

What is wrong?


====== C++ code : BEGIN ======

------ bar.h file : Fragment ------
class Foo
{
[---omitted---]

  public :
    bool foo (const Foo* const) const;

[---omitted---]
}
-----------------------------------


------ bar.cpp file : Fragment ------
[---omitted---]



[---omitted---]
-------------------------------------

====== C++ code : END ========


====== Compilation : BEGIN ======

$ sc -I. -I\dm\stlport\stlport -c bar.cpp
  mem_fun(&Foo::foo);

bar.cpp(255) : Error: need explicit cast for function parameter 1 to get
from: bool ( Foo::*member func)(const Foo*const )const
to  : bool ( Foo::*member func)(const Foo*)const
 mem_fun(&Foo::foo),

====== Compilation : END ========

DMC still treats  func(type t) and  func(type t const)  as different 
functions. This is already on Walters to do list.
