Templates do not handle const member functions properly.  Const member
functions do work in non-template classes.

This probably occurs on all machines/OS.  I've tried it on an SGI 4D
(mips-sgi-irix4) running Irix 4.0.1 and a Intel '386 (i386-sysv)
running vanilla SysV 3.2.

The sample source file is below.  The command line to show the problem
is

% g++ -DKONST=const -c bug.cc
bug.cc: In function `int  main ()':
bug.cc:12: template for method `bar' doesn't match any in class `Foo<int>'

Dropping off the -DKONST=const compiles the file successfully.

============================================================================
#ifndef KONST
#define KONST
#endif

// Demonstation purposes only.  I don't really write code like this.

template<class T> class Foo {
public:
    int bar() KONST;
private:
    int _n;
};

template<class T> int Foo<T>::bar() KONST
{
    return _n;
}

int main()
{
    // Use the template to generate the definitions for an
    // instantiation of Foo<T>
    Foo<int> f;
}
