[MSVC 6.0] std::has_facet, std::use_facet broken
------------------------------------------------

         Key: STDCXX-212
         URL: http://issues.apache.org/jira/browse/STDCXX-212
     Project: C++ Standard Library
        Type: Bug

  Components: 22. Localization  
    Versions: 4.1.2, 4.1.3    
 Environment: MSVC 6.0
    Reporter: Martin Sebor


Moved from the Rogue Wave bug tracking database:

****Created By: sebor @ Jun 16, 2004 12:17:37 PM****
The example manual/hasfacet.cpp prints 'false\nfalse\n' when compiled with MSVC 6.0. This
is due to the interaction of two bugs: PR #27947 and PR #28102 which prevents has_facet from
using the workaround mentioned in PR #27947 (using the default argument). This effectively
means that std::has_facet and std::use_facet are pretty much useless.

#include <ios>        // for boolalpha 
#include <iostream>   // for cout, endl
#include <locale>     // for has_facet()

#include <examples.h>


// dummy facet, must derive from locale::facet
// and define a static member of type locale::id
struct my_facet: public std::locale::facet
{
    static std::locale::id id;
};

std::locale::id my_facet::id;


int main ()
{
    // see if ctype<char> is contained in the locale imbued in cout
    std::cout << std::boolalpha
              << std::has_facet<std::ctype<char> >(std::cout.getloc ())
              << std::endl;
 
    // see if my_facet is contained in the locale imbued in cout
    std::cout << std::has_facet<my_facet>(std::cout.getloc ())
              << std::endl;

    return 0;
}
