regex bug/fix

From: David Abrahams (abrahams_at_[hidden])

Here is a transcript of an exchange I had with Metrowerks' lead compiler
engineer:

I think that the error message is correct. The problem can be simplified to

namespace re_detail {

    struct c_traits_base {
    protected:
        static void do_lookup_collate();
    };

    struct c_regex_traits : c_traits_base {
        static void lookup_collatename();
    };

    void c_regex_traits::lookup_collatename()
    {
        re_detail::c_traits_base::do_lookup_collate();
    }

}

"re_detail::c_traits_base::do_lookup_collate();" is not legal because
"do_lookup_collate" is found by namespace access that is using a re_detail
namespace qualification.

The example will compile when you change the call to
"c_traits_base::do_lookup_collate();" so that the name is found in a base
class lookup.
