    c++: more-specialized test
    
    I noticed the need for this testcase while working on PR102629; since there
    is no information about the target type, we don't want to choose the most
    specialized overload.
    
    gcc/testsuite/ChangeLog:
    
            * g++.dg/cpp0x/auto56.C: New test.
