9	config_info ambiguity error	ejames-beckham	jmaurer	"{{{
  I am doing internal testing on a pre-release version 
of the Borland C++ compiler.
  config/test/config_info.cpp generates an ambiguity 
with Borland C++ 5.5.1 when using the STLPort library 
in place of the currently shipping RogueWave.  I see 
that other highly-conformant compilers are also 
failing this test.  I have confirmed that with g++ 
2.95 the error given is the same as the error I see 
with Borland's compiler (w/STLPort).
  Here is a code sample that I narrowed from 
config_info.cpp:

#include<wchar.h>
#include<functional>
template<class S,class>class AA: unary_function <int, 
S>{};
template<class S,class T>AA<S,T>mem_fun(S(T::*)()const)
{}
class BB{public:void ff()const{}};
void test(){mem_fun(BB::ff);}

/*
Error E2015 config_test.cpp 6: Ambiguity 
between '_STL::_STL::const_mem_fun_t<BB> 
mem_fun<void,BB>(void (BB::*)() const)' 
and 'AA<void,BB> mem_fun<void,BB>(void (BB::*)() 
const)' in function test()
 */
