             Bug #: 54442
           Summary: Const overloads resolution failure
    Classification: Unclassified
           Product: gcc
           Version: 4.7.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: nikko...@hates.ms


gcc fails to take address of const overloads, possibly confused by the index_t
typedef:

$ gcc -v; cat t.cpp; gcc -c t.cpp
Using built-in specs.

namespace X {
using ::index_t;
} 

void (X::S::*f) (X::index_t) = &X::S::s;
void (X::S::*g) (X::index_t) const = &X::S::s;

t.cpp:20:45: error: no matches converting function 's' to type 'void (struct
X::S::*)(index_t)const {aka void (struct X::S::*)(int)const}'
t.cpp:6:10: error: candidates are: void X::S::s(int)

Thanks.
