           Summary: [3.4 Regression] "declaration of `operator()' as non-
                    function"
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: mckelvey at maskull dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: alphaev56-unknown-linux-gnu
  GCC host triplet: alphaev56-unknown-linux-gnu
GCC target triplet: alphaev56-unknown-linux-gnu

Something wrong with namespace lookup? locale defines float_t, I presume in std,
but error is wildly inappropriate. Error goes away if float_t is qualified with
PM::, but not with std::.
