           Summary: Misleading error message for out-of-class definition
                    of explicit conversion operator
           Product: gcc
           Version: 4.9.1
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P3

  Zusammenfassung: The GNU C++ Compiler
  Beschreibung: 
  This package contains the GNU compiler for C++.


Test program (C++11):

  struct ExplicitTest
  {
      explicit operator bool() const;
  };

  explicit ExplicitTest::operator bool() const
  {
      return true;
  }

The program is ill-formed because explicit is only allowed inside a class
definition, as per §7.1.2/6 Function Specifiers [N3376]. However, the error
message is misleading and seems not to have been updated for C++11, where
explicit conversion operators were introduced:

$ g++-4.9 -c -std=c++11 explicit_operator_bool.cxx
explicit_operator_bool.cxx:6:40: error: only declarations of constructors can
be ‘explicit’
 explicit ExplicitTest::operator bool() const
                                        ^

(Also it would probably be better to place the caret underneath "explicit".)
